Addition of nucleophilic metal complexes to mononuclear transition metal carbyne compounds; X-ray crystal structure of [PtW(µ-CC6H4-p-Me)(CO)2(PMe2Ph)2(η-C5H5)]

Abstract

Compounds containing platinum–tungsten bonds with bridging carbyne ligands are formed by reaction of the species [Pt(C₂H₄)(PR₃)₂](PR₃= PMe₃ or PMe₂Ph) with carbyne complexes [W(CR)(CO)₂(η-C₅H₅)] or [WBr(CR)(CO)₄](R = C₆H₄-p-Me); X-ray diffraction studies have established the structure of [PtW(µ-CC₆H₄-p-Me)(CO)₂(PMe₂Ph)₂(η-C₅H₅)].
