Transmetallation of the Fe3(3-X)2(CO)9 clusters (X = S, Se, or Te) under the action of (-C8H12)PtCl2 afforded new heterometallic clusters (-C8H12)Pt(3-X)2Fe2(CO)6 (2—4, respectively), which were characterized by X-ray diffraction analysis. The (-C8H12)Pt fragment in these clusters is bound to two 3-bridging chalcogen atoms X. The iron atoms are linked to each other. The coordination environment about the Pt atom is planar-square; the Pt...Fe distance is larger than 3.2 . In the synthesis of cluster 4, a new Pt complex was also obtained for which the structure (CO)2Pt(-Te)2Pt(CO)2 (5) was proposed. According to the results of differential scanning calorimetry, thermal decomposition of complex 5 gave rise only to PtTe, whereas complexes 1—4 gave products with the empirical formula Fe2PtX2C2O2. The influence of the steric effects on the geometry of the clusters is discussed. 相似文献

Transmetallation of the dichalcogenide complexes [CpMn(CO)2]2(-X2) (X = S or Se) with M(CO)5(thf) (M = Cr or W) afforded new heterometallic complexes CpMn(CO)2(-Se2)Cr(CO)5, CpMn(CO)2(-Se2)[Cr(CO)5]2, CpMn(CO)2(-X2)[W(CO)5]2 (X = S or Se), and CpMn(CO)2(-Se2)[Cr(CO)5][W(CO)5]. According to the X-ray diffraction data, their molecular structures contain the cyclic MnX2 fragments coordinated by one or two M(CO)5 groups via the X atoms. Study of thermal decomposition of the manganese complexes with different Mn : M : X ratios (M = Cr, W; X = S, Se, Te) by differential scanning calorimetry (DSC) and thermogravimetry demonstrated that this process took place at rather low temperatures (100—400 °C) and was accompanied by complete elimination of the CO groups followed by elimination of the Cp groups. At any metal to chalcogen ratio, the resulting inorganic chalcogenides contained no impurities of metal oxides and carbides. 相似文献

The reaction of [CpMn(CO)(NO)]2 (I) with an equimolar amount of tin dichloride in THF at room temperature gave the product of tin insertion into the Mn-Mn bond, the carbonyl nitrosyl complex [CpMn(CO)(NO)]2SnCl2 (II). The same complex was formed on treatment of CpMn(CO)(NO)SnCl3 with sodium borohydride. Treatment of I with an excess of anhydrous tin dichloride under the same conditions gave the trinitrosyl complex Cp2Mn2(NO)(μ-NO)2SnCl3 (III). According to X-ray diffraction, II contains a Mn-Sn-Mn chain with highly shortened Mn-Sn bonds (2.5570(2) and 2.5754(2) Å). Compound III contains a Mn-Mn-Sn chain (Mn-Mn, 2.5358(10); Mn-Sn, 2.5604(8) Å) with the Mn-Mn bond supplemented by two nitrosyl bridges and one terminal NO group. 相似文献

Treatment of ruthenium carbonyl, [Ru3(CO)12] with phenylseleno tribromide PhSeBr3 afforded a new triruthenium cluster, [(CO)10Br4Ru3(μ-SePh)2] (1). Its molecular structure was determined by single crystal XRD method (P21/c; a = 10.514(3) Å; b = 10.814(3) Å; c = 19.063(5) Å; β = 105.064(4)°; V = 2093.1(10) Å3) and shown to have two lateral Ru(CO)3Br2 units attached via two PhSe bridges to a Ru(CO)4 center forming a chain-like Ru-Se-Ru-Se-Ru cluster core. This is in contrast with a recently reported reaction of PhTeBr3 with [Ru3(CO)12] which formed a monomeric complex of ruthenium-dicarbonyl-dibromo fragment coordinating two PhTeBr ligands, [(CO)2RuBr2(PhTeBr)2]. 相似文献

A reaction of the dimer [Mn(CO)4(SPh)]2 with (PPh3)2Pt(C2Ph2) gave the heterometallic complex (CO)4Mn(μ-SPh)Pt(PPh3)2 (I) and its isomer (CO)3(PPh3)Mn(μ-SPh)Pt(PPh3)(CO) (II). A reaction of complex I with a diphosphine ligand (Dppm) yielded the heterometallic complex (CO)3Mn(μ-SPh)Pt(PPh3)(Dppm) (III). Complexes I–III were characterized by X-ray diffraction. In complex I, the single Mn-Pt bond (2.6946(3) ?) is supplemented with a thiolate bridge with the shortened Pt-S and Mn-S bonds (2.3129(5)
and 2.2900(6) ?, respectively). Unlike complex I, in complex II, one phosphine group at the Pt atom is exchanged for one CO group at the Mn atom. The Mn-Pt bond (2.633(1) ?) and the thiolate
bridge (Pt-S, 2.332(2) ?; Mn-S, 2.291(2) ?) are retained. In complex III, the Mn-Pt bond (2.623(1) ?) is supplemented with thiolate (Pt-S, 2.341(2) ?; Mn-S, 2.292(2) 0?) and Dppm bridges (Pt-P,
2.240(1)?; Mn-P, 2.245(2) ?). Apparently, the Pt atom in complexes I–III is attached to the formally double bond , as in Pt complexes with olefins. 相似文献

A reaction of the tetramer [PhTeI]4 with Fe(CO)5 gave the monomeric complex (CO)3FeI2(Ph2Te2) (I) containing a diphenyl ditelluride molecule linked with cis-tricarbonyldiiodoiron. According to X-ray diffraction data, the Fe-Te distance in complex I (2.5724(6) ?) is appreciably shorter than the sum of the covalent Fe and Te radii and the Te-Te bond (2.7705(5) ?) is only
slightly longer than that in free Ph2Te2 (2.705(1) ?). In the reaction of Fe(CO)5 with PhTeI3, a complex with PhTeI as a ligand to the transition metal atom was obtained for the first time. Unlike free PhTeI, the resulting
complex (CO)3FeI2(PhTeI) (II) is stable in air at room temperature for several days. According to X-ray diffraction data, the ligand PhTeI (Te-C 2.126(4)
?, Te-I(3) 2.7548(5) ?) is stabilized by the coordination of tellurium to both the iron (Te-Fe 2.5451(6) ?) and iodine atoms
(Te(1)-I(1) 3.1634(5) ?). The latter coordination probably involves the vacant d orbital of tellurium and the lone electron pair on the iodide ligand.

The reaction of [Cp′Cr(CO)2(μ-SBu)]2 (1) (Cp′ = MeC5H4) with (PPh3)2Pt(PhCCPh) gives Cp′Cr(CO)2(μ-SBu)Pt(PPh3)2 (2) which could be regarded as a product of the substitution of acetylene ligand at platinum by a monomeric chromium–thiolate fragment. According to the X-ray diffraction analysis 2 contains single Cr–Pt (2.7538(15)) and Pt–S (2.294(2) Å) bonds while Cr–S bond (2.274(3) Å) is shortened in comparison with ordinary Cr–S bonds (2.4107(4)–2.4311(4) Å) in 1. The bonding between Cr–S fragment and platinum atom is similar to the olefine coordination in their platinum complexes. 相似文献

A reaction of Cp′Mo(CO)3Cl(Cp′ = MeC5H4) with (PPh3)2Pt(C2Ph2) gave the heterometallic cluster Cp′Mo(μ-CO)2(C2Ph2)Pt2(PPh3)2(CO)Cl (I) as the sole product. According to X-ray diffraction data, complex I contains single Pt-Mo bonds (2.7962(5) and
2.7699(5) ?) but no Pt-Pt bond (Pt…Pt 2.9746(3) ?). The coordinated diphenylacetylene molecule forms two Pt-C σ-bonds (2.054(6)
and 2.083(5) ?) and a π-bond to the Mo atom (Mo-C 2.265(6) and 2.272(5) ?; C≡C 1.387(8) ?).

The substitution of a labile THF ligand in Cr(CO)5(THF) by the Ph2Se2 molecule provided the monomeric complex Cr(CO)5(Ph2Se2) (I). The similar diiodo-tricarbonyl-iron complex (CO)3FeI2(Ph2Se2) (II) (along with [(CO)3Fe(??-SePh)3Fe(CO)3]+(I5)? (III) as a by-product) was separated upon the treatment of ??phenylselenyl iodide?? [PhSeI] with iron pentacarbonyl, Fe(CO)5. Complex II is isostructural with the known tellurium-containing analogue, (CO)3FeI2(Te2Ph2). The latter have provided the dimeric tellurophenyl bridged iodo-tricarbonyl-iron complex [(CO)3IFe(??-TePh)]2 (IV) under action of the excess of Fe(CO)5. Its bromide analogue [(CO)3BrFe(??-TePh)]2 (V) was prepared upon the treatment of PhTeBr with the excess of Fe(CO)5. The reaction of [PhSeI] with Re(CO)5Cl afforded only [(CO)6Re2(??-I)2(??-Se2Ph2)] (VI) in contrast to the (CO)3Re(PhTeI)3(??3-I) formation in similar known reaction of [PhTeI]. The molecular and crystal structures of I?CVI is discussed. 相似文献

Stepwise decarbonylation of the platinum complex with cymanthrenylthiolate ligands cis-(Ph3P)2Pt[(SC5H4)Mn(CO)3]2 (1) affords the cis-(Ph3P)2Pt[(SC5H4)Mn(CO)3]-[(SC5H4)Mn(CO)2] (2) and cis-(Ph3P)2Pt[(SC5H4)Mn(CO)2]2 (3) complexes. The replacement of one carbonyl group at the manganese atom with the lone electron pair of sulfur is accompanied
by the formation of a new Mn-S bond giving rise to an unusual norbornane-type core. Complexes 1–3 were characterized by elemental analysis and IR spectroscopy. The structures of complexes 1–3 were established by single-crystal X-ray diffraction.
