A new one-dimensional coordination polymer, [Pb(phen)(ANS)2]n (ANS = 2-ami- nonaphthalene-1-sulfonate, phen = 1,10-phenanthroline), has been prepared by hydrothermal synthesis and structurally characterized by elemental analysis, IR and single-crystal X-ray diffrac- tion. The results determined by XRD reveal that the complex crystallizes in monoclinic, space group P21/c with a = 16.8374(14), b = 16.9825(14), c = 9.9392 (8) , β = 95.9830(10)o, V = 2826.5(4) 3, Mr = 831.86, Dc = 1.955 g/cm3, μ(MoKα) = 6.173 mm-1, F(000) = 1624, Z = 4, the final R = 0.0272 and wR = 0.0694 for 4305 observed reflections (I > 2σ(I)). In the complex, the adjacent lead(II) ions are bridged through the oxygen atoms of sulfonate groups in a syn-syn conformation, yielding an infinite zigzag chain. And the intermolecular N–H···O hydrogen bonds link the chains into two-dimensional layered networks, which are further assembled into a separate two-layer-film-like packing structure.  相似文献

1 INTRODUCTION Polymeric manganese complexes with fascinating topological chemistry have received considerable interest[1, 2]. The complexation of phen with man- ganese ion gives rise to a wide variety of coordi- nation complexes; however, (phen)Mn coordina- tion polymers are rare since the chelation of phen results in 1 to 3 5-membered chelating rings, ob- structing the way towards the coordination poly- mer. Similar situation has also been observed for 2,2?-bipyridine (bpy) which has si…  相似文献

A one-dimensional zinc-containing coordination polymer, [Zn2(NBA)2(4,4′-bipy)]n (NBA = 3-nitrobenzoic acid, 4,4′-bipy = 4,4′-bipyrindine), has been solvothermally synthesized and characterized by single-crystal X-ray diffraction, IR and elemental analysis. The crystal structure is of monoclinic, space group C2/c with a = 24.6478(2), b = 14.0964(3), c = 11.4275(2)A, β=108.7870(10)°, V = 3758.89(11) ,A^3, C38H20N6O16Zn2, Mr = 947.34, Z = 4, De = 1.674 g/cm^3 μ= 1.363 mml, F(000) = 1912, R = 0.0720 and wR = 0.2277 for 2841 observed reflections (I 〉 2σ(I). In this compound, NBA in syn-syn coordination mode bridges zinc centers into dimericzinctetracarboxylate [Zn2(COO)4] secondary building units (SBUs) which are linked through μ-4,4′-bpy affording 1D alternating chains. These adjacent chains are further stacked through intermolecular π...π interactions to form a 3D framework.  相似文献

A new decanuclear silver(I) compound Ag108‐S)(dtp)8 [dtp=S2P(OEt)2] was isolated from a reaction mixture containing W2S4(dtp)2 and AgN03, and its solid‐state molecular structure was determinated by X‐ray crystallography. The crystallographic study revealed that the compound contains a distorted mono‐capped quasi‐prism [Agio] with an octat‐bridging S atom at the center of the prism. The compound (C32H80Ag10O16P8S17, Mr=2592.46) crystallizes in the monoclinic P21/n space group, with a = 1.5111(5) nm, b=2.3656(8) nm, c=2.284(1) nm, β= 96.88(3)°, V=8.107(5) nm3, Z=4 and D,=2.12 g · cm?3. The solution using direct method and full‐matrix least‐squares refinement led to R=0.066, Rw=0.078 for 3928 reflections with I3σ(I).  相似文献

(C5H4SiMe2^tBu)2Ln^nBu reacted with 1 equiv, of elemental sulfur in toluene at ambient temperature to yield the corresponding lanthanocene thiolates [(C5H4SiMe2^tBu)2Ln(μ-S^nBu)]2 (Ln = Y (1), Er (2)). Complexes 1 and 2 have been characterized by elemental analysis, IR, mass spectroscopy and X-ray single-crystal diffraction analysis. Both complexes are of monoclinic with space group P21/c, formula C52H94S2Si4Y2 1 (C52H94S2Si4Er2 2) Mr = 1073.57 (1230.27), a = 8.495(2) (8.41(2)), b = 26.913(8) (26.67(7)), c = 13.756(4) (13.68(4)) A, α = 90(90), β = 101.184(5) (101.57(4)), γ = 90 (90)°, V= 3085.1(15) (3007(14)) A^3, Dc = 1.156 (1.359) g·cm^-3, Z= 2 (2), F(000) = 1144 (1260), μ = 2.046 (2.951) cm^-1, R = 0.0687 (0.0749) and wR = 0.1306 (0.1507) for observed reflections with I 〉 2σ(I). X-ray structures of 1 and 2 definitively prove that only one sulfur atom is inserted into the Ln-C(^nBu) bond, forming a thiolate ligand.  相似文献

A new mononuclear tin(IV) complex [Sn(edt)2L]·CH2Cl2 (edt = ethane-1,2-dithio- late, L = di-2-pyridyl-ketone p-phenyldiamine) was obtained by a one-pot reaction which involves in situ formation of a new Schiff-base ligand L. The title compound (C22H24Cl2N4S4Sn) crystallizes in monoclinic, space group P21/n with a = 13.438(1), b = 12.2657(10), c = 17.1477(13) (A), β = 99.323(1)o, V = 2789.1(4) (A)3, Z = 4, Mr = 662.28, Dc = 1.577g/cm3, F(000) = 1328, μ = 1.426 mm(1, the final R = 0.0450 and wR = 0.1077 for 3868 observed reflections (I > 2σ(I)). In the title compound, Sn4+ ion is six-coordinated with four sulfur atoms of two edt ligands and two nitrogen atoms of the ligand di-2-pyridyl-ketone p-phenyldiamine to form a highly distorted octahedron.  相似文献

A 2D lead(II) coordination polymer [Pb2(phen)2(N3)3(ClO4)]n,( 1 ) containing 1,10‐phenanthroline (phen) and two different anions, has been synthesized and characterized by elemental analysis, IR and 1H NMR spectroscopy and X‐ray crystallography. The single‐crystal X‐ray data show two different kinds of Pb2+ ions with coordination numbers of eight, Pb1 = PbN6O2 and Pb2 = PbN8, with hemidirected and holodirected structures, respectively. The supramolecular features in 1 is negiotated through the weak but directional C‐H···O and C‐H···N interactions and aromatic π–π stacking interactions.  相似文献

A new fluorinated polystyrene bearing a p-sulbstiuted perfluoro[1-(2-fluorosulfonylethoxy)]ethyl group was synthesized via one-electron oxidation of polystyrene by perfluoro[2-(2-fluorosulfonylethoxy)]propionyl peroxide at different peroxide to polystyrene molar ratios.The yield of perfluoroalkylation decreases with the increase of the reactant molar ratio.The modified polymer has been characterized by various techniques:the ring pefluoro[1-(2-fluorosulfonylethoxy)]ethylation has been proved by FT-IR and ^19FNMR;the X-ray photoelectron spectra(XPS) show the maximum binding energy of F18,O18,C18(two kinds of carbon atoms,namely C-H and C-F)and S2p,respectively; desulfonylation of the fluorinated polystyrene appearing at 217℃ has been found by its thermogravimetric analysis (TGA).The determinations of contact angle,refractive index and glass transition temperature of the modified polymer have disclosed that when the contact angle increases with the increase of the molar ratio,the refractive index and glass transition temperature decrease.The polydispersity values indicate that the degradation of the polymer chains did not occur during the reaction.  相似文献

[Zn(o-bda)(phen)(H2O)]n·nH2O (C22H20N2O6Zn) (1) [where o-bda is o-phenylenediacetic acid dianion and phen is 1,10-phenanthroline] crystallizes in triclinic system, space group P1 with a=0.826 5(4) nm, b=1.042 4(5) nm, c=1.238 1(6) nm, α=76.987(9)°, β=70.987(9)°, γ=78.281(8)°, V=0.9728(8) nm3, Z=2, Dc=1.617 g·cm-3, μ=1.308 mm-1 and F(000)=488. Zn(Ⅱ) ion has a distorted trigonal bipyramid coordination geometry formed by two carboxyl O atoms from two different o-bda groups, two N atoms from the phen ligand and one terminal water molecule. Adjacent Zn(Ⅱ) ions are interlinked by o-bda groups into a infinite zigzag chain structure with a Zn…Zn distance of 0.825 6(4) nm. The adjacent zigzag chains may also be paired under direction of supramolecular recognition and attraction through both π-π stacking and hydrogen bonding interactions into molecular zippers, which further interlinked into a three-dimensional supramolecular network by these noncovalent interactions.

A novel Fe(Ⅱ) coordination polymer [Fe(L)(trans-1,4-chdc)]n has been hydrothermally synthesized by using 1,4-cyclohexanedicarboxylic acid (1,4-H 2 chdc) and 2-(2-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline (L). Crystallographic data: monoclinic, space group C2/c with a=14.571(5), b=32.389(6), c=10.948(5) , β=115.186(5)°, V=4676(3)3 , Z=8, C27H21FFeN4O4 , Mr=540.33, Dc=1.535 g/cm3 , F(000)=2224, μ(MoKa)=0.697 mm-1 , R=0.0462 and wR =0.1110. The two kinds of trans-1,4-chdc ligands link neighboring Fe(Ⅱ) atoms to yield a two-dimensional layer structure. The π-π interactions between the L ligands of neighboring layers result in a three-dimensional supramolecular architecture. The IR and UV-vis spectra of the compound have been investigated in detail.  相似文献
