Chemistry of Polynuclear Metal Complexes with Bridging Carbene or Carbyne Ligands. Part 93. Synthesis of Heteropolynuclear Metal Compounds with Chains of Seven to Eleven Metal Atoms; Crystal Structure of (Mo2W3Pt6(Mu3-CMe)3(Mu3-CC6H4Me-4)2(CO)10(PMe2Ph)4(Eta-C5H5)5).

摘要

We have described rational procedures for preparing polynuclear metal complexes in which from three to seven metal atoms are linked to form chain-like structures. In these species the spines of the molecules consist of metal-metal bonds (W-Pt, Mo-Pt, W-Ni, or Mo-Ni) bridged by alkylidyne groups. The syntheses depend for their success on an isolobal mapping of metal-ligand fragments with organic groups, and the generality of the methodology has recently been demonstrated by its extension to W-Rh chain systems.
