Metal Sulfur-Nitrogen Compounds. 19. Novel Complexes of CuI with the S3N? Chelate Ligand. Preparation and Structure of [Ph4As][Cu(S3N)(CN)], [(Ph3P)2N][Cu(S3N)(S7N)], and [Ph4As]2[(S3N)Cu(S2O3)Cu(S3N)] In alkaline media S7NH reacts with Cu salts to yield different products. With Cu(CN) the ion [Cu(S3N)(CN)]? is formed, which was isolated as the [Ph4As]+ salt. The crystals are monoclinic, space group P21/c, a = 10.499(5), b = 13.418(6), c = 18.032(8) Å, β = 91.84°(3), Z = 4. Besides the known complex ions [Cu(S3N)2]? and [Cu(S3N)Cl]? still some more may be obtained when CuCl2 is reacted with S7NH: Under special conditions the S7N ring is partly preserved, and [Cu(S3N)(S7N)]? is formed. Its sparingly soluble [(Ph3P)2N]+ salt is monoclinic, space group P21/n, a = 9.335(6), b = 30.984(11), c = 15.108(8) Å, β = 102.87°(4), Z = 4. Using a longer reaction time a dinuclear complex [(S3N)Cu(S2O3)Cu(S3N)]? ? results from the reaction of CuCl2 with S7NH. The two Cu atoms are bridged by an S atom of the S2O3? ? anion. The [Ph4As]+ salt of the dinuclear complex anion is triclinic, space group P1 , a = 11.226(6), b = 12.423(6), c = 19.000(10) Å, β = 76.47°(4), β = 83.98°(4), γ = 84.71°(4), Z = 2. In all these compounds the coordination of CuI is trigonal-planar, the S3N? chelate group coordinates the Cu in the usual way by two S atoms.  相似文献

The reaction of S4N3Cl with metal salts leads to complexes containing the S3N?chelating ligand, a reaction which proceeds smoothly especially in an alkaline medium. Thus we were able to prepare, by the reaction of CuCN with S4N3Cl and [Ph6P2N]OH (Ph = phenyl), the salt [Ph6P2N][Cu3(S3N)2(CN)2], a compound in which the anions build a bidimensional network through supplementary Cu - S contact interactions. The salt is monoclinic, space group C2/c, a = 18.960, b = 14.651 and c = 15.400 Å, β = 101.03° and Z = 4. Metal Sulfur Nitrogen Compounds. 22. S4N3Cl as a Starting Compound for the Preparation of Complexes Containing the S3N? Ligand. Complexes [Ph6P2N] [Cu3(S3N)2 (CN)2] and [Ph4As] [(CuS3N)2 (CN)] In contrast, the reaction of CuN with S4N3Cl and [Ph4As]OH led to the compound [Ph4As][(CuS3N)2(CN)], monoclinic, space group C2/c, a = 18.478, b = 6.405, c = 27.051 Å, β = 119.50°, Z = 4. In the centrosymmetric anion the two Cu(S3N) groups are linked together by disordered CN? groups. An additional linkage results from Cu - Cu contact interactions, with d = 2.84 Å.  相似文献

Metal Sulfur Nitrogen Compounds. 20. Reaction Products of PdCl2 and Pd(CN)2 with S7NH. Preparation and Structure of the Complexes [Ph6P2N][Pd(S3N)(S5)] and X[Pd(S3N)(CN)2] X = [Me4N]+, [Ph4P]+ With PdCl2 and [Ph6P2N]OH S7NH forms the complex salt [Ph6P2N][Pd(S3N)(S5)], which could be isolated in two modifications (α- and β-form). The α-form is triclinic, a = 9.347(4), b = 14.410(8), c = 15.440(11) Å, α = 76.27°(5), β = 77.06°(4), γ = 76.61α(4), Z = 2, space group P1 . The β-form is orthorhombic, a = 9.333(2), b = 17.659(4), c = 23.950(6) Å, Z = 4. The structure of the metal complex is the same in the two modifications. One S3N? and one S52? are coordinate as chelate ligands to Pd. From S7NH, Pd(CN)2, and XOH X = [(CH3)4N]+ and [(C6H5)4P]+ the salts X[Pd(S3N)(CN)2] were formed. The (CH3)4N-salt is isomorphous with the analogous Ni compound described earlier, the (C6H5)4P-salt is triclinic, a = 9.372(4), b = 10.202(5), c = 13.638(6) Å, α = 86.36α(4), β = 85.66°(4), γ = 88.71°(4), Z = 2, space group P1 . One S3N? chelate ligand and two CN? ions are bound to Pd. In all these complexes the coordination of Pd is nearly square planar.  相似文献

Preparation, Spectroscopic Characterization, and Crystal Structures of [(C5H5N)2CH2][PtCl5(SCN)] and cis -[(C5H5N)2CH2][PtCl4(SCN)2] By treatment of [PtCl6]2– with SCN in aqueous solution a mixture of chlorothiocyanatoplatinates(IV) is formed, from which [PtCl5(SCN)]2– and cis-[PtCl4(SCN)2]2– have been separated by ion exchange chromatography on diethylaminoethyl cellulose. X-Ray structure determinations on single crystals of [(C5H5N)2CH2][PtCl5(SCN)] ( 1 ) (tetragonal, space group P 43, a = 7.687(1), c = 29.698(4), Z = 4) and cis-[(C5H5N)2CH2][PtCl4(SCN)2] ( 2 ) (monoclinic, space group P 21/n, a = 11.2467(9), b = 15.0445(10), c = 11.3179(13), β = 92.840(9)°, Z = 4) show, that the thiocyanate groups are coordinated via S atoms with average Pt–S distances of 2.339 Å and Pt–S–C angles of 104.7° up to 107.1°. Using the molecular parameters of the X-ray determinations the low temperature (10 K) IR and Raman spectra have been assigned by normal coordinate analyses. The valence force constants of the S–Pt–Cl˙ axes are fd(PtS) = 1.81 ( 1 ) and 1.87 ( 2 ), fd(PtCl × ) = 1.77 ( 1 ) and 1.81 ( 2 ), of the Cl–Pt–Cl axes are fd(PtCl) = 1.93 ( 1 ) and 1.90 mdyn/Å ( 2 ). The 195Pt NMR spectra from dichlormethane solutions exhibit each one sharp signal at 3975.6 ( 1 ) and 3231.6 ppm ( 2 ), respectively.  相似文献

Characterization of Distortional Isomers of the Anions Pentacyano-oxo-molybdate(IV) and of Tetracyano-aqua-oxo-molybdate(IV) in the Solid State. Crystal Structures of [(C6H5)4P]3[MoO(CN)5] · 7 H2O (green), [(C6H5)4As]2[MoO(OH2)(CN)4] · 4 H2O (blue), and [(C6H5)4P]2[MoO(OH2) (CN)4] · 4 H2O (green) Preparation of a series of salts containing the new pentacyano-oxo-molybdate(IV) anion is described: Cs2H[MoO(CN)5] (blue), [(CH3)4N]2H[MoO(CN)5] · 2 H2O (blue) and [Cr(en)3] [MoO(CN)5] · 4 H2O (green). The green [(C6H5)4P]3[MoO(CN)5] · 7 H2O crystallizes triclinic in the space group P1 . The molybdenum(IV) center is in an pseudo-octahedral environment of a terminal oxo-group (d(Mo?O); 1.705(4) Å), a CN? group in the trans-position (d(Mo? C): 2.373(6) Å), and four equatorial CN? groups (averaged d(Mo? C): 2.178 (Å). The blue and green salts exhibit v(Mo?O) stretching frequencies at 948 cm?1 and 920 cm?1, respectively. Blue and green salts containing the [MoO(OH2)(CN)4]2? anion and [(C6H5)4P]+ or [(C6H5)4As]+ cations have been prepared and characterized by single crystal crystallography. [(C6H5)4P]2[MoO(OH2)(CN)4] · 4 H2O (green) and [(C6H5)4As]2[MoO(OH2)(CN)4] · 4 H2O (blue) crystallize monoclinic in the space group C—P21/n. They are considered to be distortional isomers of the complex anion: the green species has a Mo?O bond distance of 1.72(2) Å whereas for the blue species d(Mo?O) = 1.60(2) Å is found; the corresponding v(Mo?O) frequencies are at 920 cm?1 and 980 cm?1.  相似文献

Syntheses and Crystal Structures of [(Ph3As)2CCN–MnBr3], [(Ph3As)2CCN–CoBr3], and [(Ph3As)2CCN]+CuBr2 The di(arsa)acetonitrilium bromide [(Ph3As)2CCN]Br reacts with the anhydrous dibromides of manganese and cobalt in acetonitrile to form the molecular complexes [(Ph3As)2CCN–MBr3] [M = ( 1 ), Co( 2 )] with zwitterionic structures. With copper(I)bromide, however, the ionic compound [(Ph3As)2CCN]+CuBr2 ( 3 ) is formed. All complexes are characterized by IR spectroscopy and by crystal structure analyses. 1 and 2 crystallize isotypically with each other in the space group P 1 with two formula units per unit cell. The MBr3 fragments in the molecular complexes are connected to the N atom of the [(Ph3As)2CCN]+ cation showing bond angles C–N–Mn of 156.9° and C–N–Co of 161°, and distances Mn–N of 215.6 pm and Co–N of 201 pm. In 3 , on the other hand, (space group C2/c, Z = 4) the ions [(Ph3As)2CCN]+ and the linear Br–Cu–Br ion are to be found concurrent but separate.  相似文献

Turquoise crystals of the title salt, propyl­ammonium di‐μ‐thio‐1:2κ4S‐di­thio‐2κ2S‐tris(2‐amino­ethyl)­amine‐1κ4N‐anti­mony(V)­nickel(II), (C3H10N)[NiSbS4(C6H18N4)] or [PAH][Ni(tren)SbS4] [where tren is tris(2‐amino­ethyl)­amine and PA is propyl­amine], were synthesized under solvothermal conditions by reacting [Ni(tren)2]Cl2, Sb and S in a solution of PA. The NiII ion is octahedrally surrounded by four N atoms of the tetradentate tren mol­ecule and by two S atoms of the tetrahedral [SbVS4]3? anion, thus forming the anionic [Ni(tren)SbS4]? part of the compound. Charge balance is achieved through the PAH+ cation. An extended intermolecular hydrogen‐bonding network is observed between the anion and the cation.  相似文献

Crystal Structures of the Fluorochloroplatinates(IV) cis-[(C5H5N)2CH2][PtF4Cl2], trans-[(C5H5N)2CH2][PtF4Cl2] · H2O, and [(C5H5N)2CH2][PtF5Cl] The complex ions cis-[PtF4Cl2]2?, trans-[PtF4Cl2]2? and [PtF5Cl]2? have been synthesized by stereoselective ligand exchange reactions utilizing the trans effect and are separated by ion exchange chromatography on diethylaminoethyl cellulose. These anions form stable AB-type salts with the doubly charged cation dipyridiniomethane, [(C5H5N)2CH2]2+. X-ray structure determinations on single crystals of cis-[(C5H5N)2CH2][PtF4Cl2] ( 1 ) (monoclinic, space group P21/n with a = 10.379(10), b = 9.635(2), c = 13.738(2) Å, β = 99.142(10)°, Z = 4), trans-[(C5H5N)2CH2][PtF4Cl2] · H2O ( 2 ) (triclinic, space group P1 with a = 7.757(4), b = 10.059(7), c = 10.408(6) Å, α = 82.49(5), β = 68.92(4), γ = 75.46(4)°, Z = 2) and [(C5H5N)2CH2][PtF5Cl] ( 3 ) (orthorhombic, space group Pnma with a = 10.394(3), b = 13.320(2), c = 9.2694(10) Å, Z = 4), reveal the perfect ordering of the anion sublattice. The stronger trans influence of Cl compared with F is observed in asymmetric axes $ {\rm F}^ \bullet $? Pt? Cl′. The bond lengths Pt? $ {\rm F}^ \bullet $ are 0.026 Å (1.4%) longer and the Pt? Cl′ distances are 0.078 Å (3,3%) shorter in comparison with those of symmetrically coordinated axes. The weakening of the Pt? $ {\rm F}^ \bullet $ bond and the strengthening of the Pt? Cl′ bond is better recognizable from shifts of the stretching vibrations by 8% to lower and by 13% to higher frequencies, respectively. Correspondingly, the valence force constants are found to be 15% lower and 22% higher. The trans influence is observed most distinctly in the 19F-nmr spectra exhibiting the coupling constant 1J($ {\rm F}^ \bullet $Pt) to be 29% smaller than 1J(FPt).  相似文献

The anion [Ag(S9)]? shows a symmetric conformation of a ten-membered ring system. 1 crystallizes in the triclinic space group P1 (a = 1383.8(4), b = 1429.5(4), c = 1540.5(5) pm, α 62.38(2), β 68.05(2), γ 65.86(2)°, V = 2399.1 · 106 pm3, Z = 2; R = 0.077 for 5433 independent reflections (F0 > 3.92 σ(F0))).  相似文献

Synthesis and Crystal Structure of the Complexes [(n‐Bu)4N]2[{(THF)Cl4Re≡N}2PdCl2], [Ph4P]2[(THF)Cl4Re≡N‐PdCl(μ‐Cl)]2 and [(n‐Bu)4N]2[Pd3Cl8] The threenuclear complex [(n‐Bu)4N]2[{(THF)Cl4Re≡N}2 PdCl2] ( 1 ) is obtained in THF by the reaction of PdCl2(NCC6H5)2 with [(n‐Bu)4N][ReNCl4] in the molar ration 1:2. It forms orange crystals with the composition 1· THF crystallizing in the monoclinic space group C2/c with a = 2973.3(2); b = 1486.63(7); c = 1662.67(8)pm; β = 120.036(5)° and Z = 4. If the reaction is carried out with PdCl2 instead of PdCl2(NCC6H5)2, orange crystals of hitherto unknown [(n‐Bu)4N]2[Pd3Cl8] ( 3 ) are obtained besides some crystals of 1· THF. 3 crystallizes with the space group P1¯ and a = 1141.50(8), b = 1401.2(1), c = 1665.9(1)pm, α = 67.529(8)°, β = 81.960(9)°, γ = 66.813(8)° and Z = 2. In the centrosymmetric complex anion [{(THF)Cl4Re≡N}2PdCl2]2— a linear PdCl2 moiety is connected in trans arrangement with two complex fragments [(THF)Cl4Re≡N] via asymmetric nitrido bridges Re≡N‐Pd. For Pd(II) thereby results a square‐planar coordination PdCl2N2. The linear nitrido bridges are characterized by distances Re‐N = 163.8(7)pm and Pd‐N = 194.1(7)pm. The crystal structure of 3 contains two symmetry independent, planar complexes [Pd3Cl8]2— with the symmetry 1¯, in which the Pd atoms are connected by slightly asymmetric chloro bridges. By the reaction of equimolar amounts of [Ph4P][ReNCl4] and PdCl2(NCC6H5)2 in THF brown crystals of the heterometallic complex, [Ph4P]2[(THF)Cl4Re≡N‐PdCl(μ‐Cl)]2 ( 2 ) result. 2 crystallizes in the monoclinic space group P21/n with a = 979.55(9); b = 2221.5(1); c = 1523.1(2)pm; β = 100.33(1)° and Z = 2. In the central unit ClPd(μ‐Cl)2PdCl of the centrosymmetric anionic complex [(THF)Cl4Re≡N‐PdCl(μ‐Cl)]22— the coordination of the Pd atoms is completed by two nitrido bridges Re≡N‐Pd to nitrido complex fragments [(THF)Cl4Re≡N] forming a square‐planar arrangement for Pd(II). The distances in the linear nitrido bridges are Re‐N = 163.8(9)pm and Pd‐N = 191.5(9)pm.  相似文献

The reaction of Ph3SnCl, (R4N)2[Mo6O19] and (R4N)OH in a molar ratio of 6:1:10 leads to the formation of (R4N)[(Ph3Sn)MoO4] (R = nPr ( 1 ), nBu ( 2 )). Compounds 1· CH3CN and 2 have been charactarized by IR spectroscopy and single crystal X‐ray diffraction. 1· CH3CN forms orthorhombic crystals, space group P212121 with a = 1339.9(2), b = 1508.9(2), c = 1733.2(3) pm. 2 crystallizes in the monoclinic space group P21 with a = 1342.6(2), b = 2280.3(4), c = 1344.0(2) pm, β = 118.34(1). Both compounds 1 and 2 consist of isolated R4N+ cations and polymeric $\rm^{1}_{\infty}$ [(Ph3Sn)MoO4] chains with an alternating arrangement of Ph3Sn+ and MoO42– groups. Treatment of (Ph3Sn)2MoO4 with bis(ethylenediamine)copper(II) succinate yields [Cu(en)2(Ph3Sn)2(MoO4)2] ( 3 ). The zinc derivative [Zn(en)2(Ph3Sn)2(MoO4)2] ( 4 ) is obtained similarly by reaction of (Ph3Sn)2MoO4 with bis(ethylenediamine)zinc(II) formiate. Compounds 3· 2DMF · EtOH and 4· 2DMF · EtOH crystallize in the monoclinic space group P21/n with a = 1998.0(2), b = 1313.3(1), c = 2181.6(2) pm, β = 90.97(1)° for 3 and a = 2015.4(1), b = 1316.7(1), c = 2157.0(1) pm, β = 90.40(1)° for 4 . Like in the cases of 1 and 2, polymeric $\rm^{1}_{\infty}$ [(Ph3Sn)MoO4] chains are observed. The [M(en)2]2+ units (M = Cu, Zn) act as linkers between the $\rm^{1}_{\infty}$ [(Ph3Sn)MoO4] chains to give 2D layer structures with (6, 3) net topology.  相似文献

Synthesis, Crystal Structure, and Properties of the Complexes [(H2O)Cl4Os≡N‐IrCl(C5Me5)(AsPh3)], [(Ph3Sb)Cl4Os≡N‐IrCl(C5Me5)(SbPh3)], [(Ph3Sb)2Cl3Os≡N‐IrCl(COD)] and [{(Me2PhP)2(CO)Cl2Re≡N}2ReNCl2(PMe2Ph)] The dinuclear complexes [(H2O)Cl4Os≡N‐IrCl(C5Me5)(AsPh3)]·H2O ( 1 ·H2O), [(Ph3Sb)Cl4Os≡N‐IrCl(C5Me5)(SbPh3)] ( 2 ), and [(Ph3Sb)2Cl3Os≡N‐IrCl(COD)] ( 3 ) result from the reaction of the nitrido complexes [(Ph3As)2OsNCl3] and [(Ph3Sb)2OsNCl3] with the iridium compounds [IrCl2(C5Me5)]2 and [IrCl(COD)]2 in dichloromethane. 1 crystallizes as 1 ·H2O in form of green platelets in the monoclinic space group Cm and a = 1105.53(6); b = 1486.76(9); c = 2024.88(10) pm, β = 97.191(4)°, Z = 4. The formation of 1 in air involves a ligand exchange, and the coordination of a water molecule in trans position to the Os‐N triple bond. The resulting complex fragments [(H2O)Cl4Os≡N] and [IrCl(C5Me5)(AsPh3)] are connected by an asymmetric nitrido bridge Os≡N‐Ir. The nitrido bridge is characterised by an Os‐N‐Ir bond angle of 173.7(7)°, and distances Os‐N = 168(1) pm and Ir‐N = 191(1) pm. 2 crystallizes in clumped together brown platelets with the space group and a = 1023.3(3), b = 1476.2(3), c = 1872.5(6) pm, α = 74.60(2), β = 73.84(2), γ = 76.19(2)°, Z = 2. In 2 the asymmetric nitrido bridge Os≡N‐Ir joins the two complex fragments [(Ph3Sb)Cl4Os≡N] and [IrCl(C5Me5)(SbPh3)], which are formed by a ligand exchange reaction. 3 forms dark green crystals with the triclinic space group and a = 1079.4(1), b = 1172.3(1), c = 1696.7(2) pm, α = 101.192(9),β = 92.70(1), γ = 92.61(1)°, Z = 2. The distances in the almost linear nitrido bridge (Os≡N‐Ir = 175.3(7)°) are Os‐N = 171(1) pm and Ir‐N = 183(1) pm. The reaction of [ReNCl2(PMe2Ph)3] with [Mo(CO)3(NCMe)3] unexpectedly affords the trinuclear complex [{(Me2PhP)2(OC)Cl2Re≡N}2ReNCl2(PMe2Ph)] ( 4 ) as the main product. It forms triclinic brown crystals with the composition 4 ·2THF and the space group (a = 1382.70(7), b = 1498.58(7), c = 1760.4(1) pm, α = 99.780(7), β = 99.920(7), γ = 114.064(6)°, Z = 2). In the trinuclear complex, the central fragment, [ReNCl2(PMe2Ph)] is joined in trans position to two nitrido complexes [(Me2PhP)2(CO)Cl2Re≡N], giving an almost linear Re≡N‐Re‐N≡Re arrangement. The bond angles and distances in the nitrido bridges are Re‐N‐Re = 167.8(3)°, Re‐N = 171.1(8) pm and 204.2(8) pm; and Re‐N‐Re = 168.1(4)°, Re‐N = 170.9(9) and 203.5(9) pm respectively. As expected, the Re‐N bond length to the terminal nitrido ligand on the central Re atom is much shorter at 161.2(9) pm than the triple bonds of the asymmetric bridges.  相似文献

Synthesis of Copper and Silver Complexes with Pentadentate N,S and Hexadentate N,O Chelate Ligands – Characterization and Crystal Structures of {Cu2[C6H4(SO2)NC(O)]2(C5H5N)4}, {Cu2[C5H3N(CHNC6H4SCH3)2]2}(PF6)2, and {Ag[C5H3N(CHNC6H4SCH3)2]}PO2F2 In the course of the reaction of copper(II)-acetate monohydrate with 2,2′-bisbenzo[d][1,3]thiazolidyl in methanol the organic component is transformed to N,N′-bis-(2-thiophenyl)ethanediimine and subsequently oxidized to the N,N′-bis-(2-benzenesulfonyl)ethanediaciddiamide H4BBSED, which coordinates in its deprotonated form two Cu2+ ions. Crystallisation from pyridine/n-hexane yields [Cu2(BBSED)(py)4] · MeOH. It forms triclinic crystals with the space group P1 and a = 995.5(2) pm, b = 1076.1(3) pm, c = 1120.7(2) pm, α = 104.17(1)°, β = 105.28(1)°, γ = 113.10(1)° and Z = 1. In the centrosymmetrical dinuclear complex the copper ions are coordinated in a square-pyramidal arrangement by three nitrogen and two oxygen atoms. The Jahn-Teller effect causes an elongation of the axial bond by approximately 30 pm. The reactions of the pentadentate ligand 2,6-Bis-[(2- methylthiophenyl)-2-azaethenyl]pyridine BMTEP with salts of copper(I), copper(II) and silver(I) yield the complexes [CU2(BMTEP)2](PF6)2, [Cu(BMTEP)]X2 (X = BF, C1O) and [Ag(BMTEP)]X (X = PO2F, ClO). [Cu2(BMTEP)2](PF6)2 crystallizes from acetone/diisopropyl- ether in form of monoclinic crystals with the space group C2/c, and a = 1833.2(3) pm, b = 2267.30(14) pm, c = 1323.5(2) pm, β= 118.286(5)°, and 2 = 4. In the dinuclear complex cation with the symmetry C2 the copper ions are tetrahedrally coordinated by two bridging BMTEP ligands. The Cu? Cu distance of 278.3pm can be interpreted with weak Cu? Cu interactions which also manifest itself in a temperature independent paramagnetism of 0.45 B.M. The monomeric silver complex [Ag(BMTEP)]PO2F2 crystallizes from acetone/thf in the triclinic space group P1 with a = 768.7(3) pm, b = 1074.0(5) pm, c = 1356.8(5) pm, α = 99.52(2)°, β = 96.83(2)°, γ = 99.83(2)° and Z = 2. The central silver ion is coordinated by one sulfur and three nitrogen atoms of the ligand in a planar, semicircular arrangement. The bond lengths Ag? N = 240.4–261.7 and Ag? S = 257.2 pm are significantly elongated in comparison with single bonds.  相似文献

The Ni atom lies in the centre of symmetry and is coordinated by four S atoms of the two molecules of the ligand in a planar arrangement. Ni? S bond lengths are 2.205 and 2.226 Å resp., the angles S? Ni? S are 97.65 and 82.35° resp.  相似文献

New Phosphoraneiminato Complexes of Molybdenum and Tungsten. Crystal Structures of [(μ‐S2N2){MoCl4(NPPh3)}2], [Mo(NPPh3)4][BF4]2, [W(S)2(NPPh3)2], and [Ph3PNH2]+[SCN] The binuclear molybdenum(V)phosphoraneiminato complex [(μ‐S2N2){MoVCl4(NPPh3)}2] ( 1 ) has been prepared by the reaction of the chlorothionitreno complex [MoVICl4(NSCl)]2 with Me3SiNPPh3 in dichloromethane forming green crystals. The temperature dependent magnetic susceptibility in the range of 2–30 K shows ideal behaviour according to the Curie law with a magnetic moment of 1.60 B.M. According to the crystal structure determination 1 forms centrosymmetric molecules in which the molybdenum atoms are connected by the nitrogen atoms of the S2N2 molecule. In trans‐position to it the nitrogen atoms of the phosphoraneiminato groups (NPPh3) are coordinated with Mo–N bond lengths of 171(1) pm. The tetrakis(phosphoraneiminato) complex [Mo(NPPh3)4]‐ [BF4]2 ( 2 ) has been obtained as colourless crystal needles by the reaction of MoN(NPPh3)3 with boron trifluoride etherate in toluene solution. In the dication the molybdenum atom is tetrahedrally coordinated by the nitrogen atoms of the (NPPh3) groups with Mo–N bond lengths of 179,8–181,0(3) pm. The dithio‐bis(phosphoraneiminato) tungsten complex [W(S)2(NPPh3)2] ( 3 ) is formed as yellow crystals as well as [Ph3PNH2]+[SCN] ( 4 ) from the reaction of WN(NPPh3)3 with carbon disulfide in tetrahydrofurane in the presence of traces of water. 3 has a monomeric molecular structure with tetrahedrally coordinated tungsten atom with bond lengths W–S of 214.5(5) pm and W–N of 179(1) pm. In the structure of 4 the thiocyanate ions are associated by hydrogen bonds of the NH2 group of the [Ph3PNH2]+ ion to give a zigzag chain. 1 : Space group Pbca, Z = 4, lattice constants at –80 °C: a = 1647.9(3), b = 1460.8(2), c = 1810.4(4) pm; R1 = 0.0981. 2 : Space group P1, Z = 2, lattice constants at –80 °C: a = 1162.5(1), b = 1238.0(1), c = 2346.2(2) pm; α = 103.14(1)°, β = 90.13(1)°, γ = 97.66(1)°; R1 = 0.0423. 3 : Space group Fdd2, Z = 8, lattice constants at –80 °C: a = 3310.1(4), b = 2059.7(2), c = 966,7(1) pm; R1 = 0.0696. 4 : Space group P212121, Z = 4, lattice constants at –80 °C: a = 1118.4(1), b = 1206.7(1), c = 1279.9(1) pm; R1 = 0.0311.  相似文献

On the Crystal Structures of the Cyano Complexes [Co(NH3)6][Fe(CN)6], [Co(NH3)6]2[Ni(CN)4]3 · 2 H2O, and [Cu(en)2][Ni(CN)4] Of the three title compounds X‐ray structure determinations were performed with single crystals. [Co(NH3)6][Fe(CN)6] (a = 1098.6(6), c = 1084.6(6) pm, R3, Z = 3) crystallizes with the CsCl‐like [Co(NH3)6][Co(CN)6] type structure. [Co(NH3)6]2[Ni(CN)4]3 · 2 H2O (a = 805.7(5), b = 855.7(5), c = 1205.3(7) pm, α = 86.32(3), β = 100.13(3), γ = 90.54(3)°, P1, Z = 1) exhibits a related cation lattice, the one cavity of which is occupied by one anion and 2 H2O, whereas the other contains two anions parallel to each other with distance Ni…Ni: 423,3 pm. For [Cu(en)2][Ni(CN)4] (a = 650.5(3), b = 729.0(3), c = 796.5(4) pm, α = 106.67(2), β = 91.46(3), γ = 106.96(2)°, P1, Z = 1) the results of a structure determination published earlier have been confirmed. The compound is weakly paramagnetic and obeys the Curie‐Weiss law in the range T < 100 K. The distances within the complex ions of the compounds investigated (Co–N: 195.7 and 196.4 pm, Ni–C: 186.4 and 186.9 pm, resp.) and their hydrogen bridge relations are discussed.  相似文献

Preparation, 11B NMR, Vibrational Spectra, and Crystal Structure of [(C5H5N)2CH2][1-(O2N)B10H9] By reaction of [B10H10]2? in aqueous acetonitrile with a saturated solution of NO2 in dichloromethane [1-(O2N) · B10H9]2? and [B10H9(NO)B10H9]3? are formed which can be separated by ion exchange chromatography on diethylaminoethyl(DEAE) cellulose from the starting compound. The X-ray structure determination of [(C5H5N)2CH2][1-(O2N)B10H9] (triclinic, space group P1 , a = 7.1530(9), b = 8.3753(8), c = 15.198(2) Å, α = 96.00(1), β = 95.48(1), γ = 95.60(1)°, Z = 2) reveals the coordination of the NO2 group via N with a B1? N distance of 1.535(5) Å and an O2? N? O1 angle of 119.3(3)°. The 11B NMR spectrum exhibits the characteristic feature (1 : 1 : 4 : 4) of an apical monosubstituted B10 cluster with a strong downfield shift of the ipso-B atom at +13.4 ppm. The IR and Raman spectra show strong NO stretching vibrations at 1381 und 1420 cm?1.  相似文献

Preparation, Vibrational Spectra, and Normal Coordinate Analysis of Hexachlororhenate(V) and Crystal Structure of [P(C6H5)4][ReCl6] By oxidation of A2[ReCl6], A = [(n-C4H9)4N]+, [P(C6H5)4]+, with Cl2 in dichloromethane/trifluoracetic acid A[ReCl6] is formed. [P(C6H5)4][ReCl6] crystallizes with tetragonal symmetry, space group P4/n-C, a = 12.967(4), c = 7.6992(8) Å, Z = 2. The octahedral complexion [ReCl6]? is compressed (C4v) with the bond lengths, axial Re? Cl1 = 2.28 and Re? Cl3 = 2.24 Å, equatorial Re? Cl2 = 2.31 Å. The infrared active antisymmetric Re? Cl stretching vibration is split into v3 = 346 an v3 = 326 cm?1. The assignment of all IR and Raman modes is confirmed by a normal coordinate analysis. The different valence force constants, fd(ReCl1) = 2.09, fd(ReCl3) = 2.10, fd(ReCl2) = 1.88 mdyn/ Å result from the distortion of the octahedron. On excitation with the Ar laser line 514.5 nm a resonance Raman spectrum is observed, showing 8 overtones of v′(A1) = 382 cm?1, from which the harmonic frequency ω1 = 382.1 cm?1, the anharmonicity constant X11 = ?0.76 cm?1, and the maximum bond dissociation energy of the [ReCl6]? ion to be 138 kcal/mol, are calculated. The vibrational fine structure of the intraconfigurational transitions in the near infrared has been resolved by measuring the absorption spectrum of [(n-C4H9)4N][ReCl6] at low temperature (10 K), resulting in the assignment of the following electronic origins: Γ3(3T1g) → Γ4(3T1g): 7 512, Γ3(3T1g) → Γ1(3T1g): 7 624 and Γ3(3T1g) → Γ5(1T2g), Γ3(1Eg): 8 368 cm?1.  相似文献

Four new thioantimonates(III) with compositions [(C3H10NO)(C3H10N)][Sb8S13] ( 1 ) (C3H9NO = 1‐amino‐3‐propanol, C3H9N = propylamine), [(C2H8NO)(C2H8N)(CH5N)][Sb8S13] ( 2 ) (C2H7NO = ethanolamine, C2H7N = ethylamine, CH5N = methylamine), [(C6H16N2)(C6H14N2)][Sb6S10] ( 3 ) (C6H14N2 = 1,2‐diaminocyclohexane) and [C8H22N2][Sb4S7] ( 4 ) (C8H20N2 = 1,8‐diaminooctane) were synthesized under solvothermal conditions. Compound 1 : triclinic space group P$\bar{1}$ , a = 6.9695(6) Å, b = 13.8095(12) Å, c = 18.0354(17) Å, α = 98.367(11), β = 96.097(11) and γ = 101.281(11)°; compound 2 : monoclinic space group P21/m, a = 7.1668(5), b = 25.8986(14), c = 16.0436(11) Å, β = 96.847(8)°; compound 3 : monoclinic space group P21/n, a = 11.6194(9), b = 10.2445(5) Å, c = 27.3590(18) Å, β = 91.909(6)°; compound 4 : triclinic space group P$\bar{1}$ , a = 7.0743(6), b = 12.0846(11), c = 13.9933(14) Å, α = 114.723(10), β = 97.595(11), γ = 93.272(11)°. The main structural feature of the two atoms thick layered [Sb8S13]2– anion in 1 are large nearly rectangular pores with dimensions 11.2 × 11.7 Å. The layers are stacked perpendicular to [100] to form tunnels being directed along [100]. In contrast to 1 the structure of 2 contains a [Sb8S13]2– chain anion with Sb12S12 pores measuring about 8.9 × 11.5 Å. Only if longer Sb–S distances are considered as bonding interactions a layered anion is formed. The chain anion [Sb6S10]2– in compound 3 is unique and is constructed by corner‐sharing SbS3 pyramids. Two symmetry‐related single chains consisting of alternating SbS3 units and Sb3S3 rings are bound to Sb4S4 rings in chair conformation. Finally, in the structure of 4 the SbS3 and SbS4 moieties are joined corner‐linked to form a chain of alternating SbS4 units and (SbS3)3 blocks. Neighboring chains are connected into sheets that contain relatively large Sb10S10 heterorings. The sheets are further connected by sulfur atoms generating four atoms thick double sheets.  相似文献
