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

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.

Interaction of [Cp2Cr2(CO)4[μ-SC5H4Mn(CO)3]2 with sulphur gave binuclear complex Cp2Cr2[μ-SC5H4Mn(CO)3]2(μ-S) (I) (Cp = π-C5H5) and triangular cluster Cp3Cr3[μ-SC5H4Mn(CO)3](μ-S)2(μ3-S) (II). I was also synthesized from Cp2Cr2(μ-SCMe3)2(μ-S) and (CO)3Mn(C5H4SH). Interaction between I and Co2(CO)8 resulted in triangular mixed-metal cluster Cp2Cr2[μ-SC5H4Mn(CO)3](μ3-S)2Co(CO)2 (III). The molecular structures of I–III were determined by means of single-crystal X-ray diffraction analysis. 相似文献

Multiple supramolecular functionalities of cyclic α-alkoxy tellurium-trihalides (including Te---O, Te---X (X = Br, I) and Te---π(C=C) supramolecular synthons) afford rich crystal packing possibilities, which consequently results in polymorphism or Z’ > 1 crystal structures. Example of three crystal forms of cyclohexyl-ethoxy-tellurium-trihalides, one of which combines the packing of two others, affords a unique model to observe the supramolecular synthon evolution at the early stages of crystallization, when crystals on the way find themself at a carrefour between the evolutionally close routes, but fail to choose between two energetically close packing patterns, so taking the “middle path”, which incorporates both of them (and results in two crystallographically independent molecules). In general, this allows a better understanding of the existing structures, and an instrument to search for the new polymorphic forms. 相似文献

Thermal reaction between PhCCI and powdered Te afforded a mixture of (E)-4-iodo-2-(iodo(phenyl)-5-phenyl-1,3-ditellurofulvene (1) and (Z)-4-iodo-2-(iodo(phenyl)-5-phenyl-1-(diiodo),3-ditellurofulvene (2), which was subsequently reduced to (Z)-4-iodo-2-(iodo(phenyl)-5-phenyl-1,3-ditellurofulvene (3). Formation of 1 and 3 as the thermodynamically most stable products has been rationalized using density functional theory (DFT) calculations. Molecular structures of 1-3 were established crystallographically. In the solid state the coordination sphere of both tellurium atoms in 2 is extended by weak intermolecular Te?π interactions with the solvate molecule of toluene which completes the pseudo-trigonal bipyramidal coordination geometry around each Te atom and assembles 2 into the chains along the crystallographic c-axis. 相似文献

The structure and dynamic behavior of complex [(η5-C5H4CH3)Cr(CO)2(μ-SBu)Pt(PPh3)2] in solution was studied by multinuclear (1H, 13C, 31P) NMR spectroscopy including a phase-sensitive NOESY experiment. Increasing temperature causes rupture of the Cr-Pt bond in the three-membered ring of the complex and rotation of the S-Pt(PPh3)2 unit around the Cr-S bond line, followed by formation of a new Cr-Pt bond to close the ring. All activation parameters for this dynamic process have been determined. 相似文献
