Phenylvinylidene Clusters Containing ReFePt Metal Cores and Chelate Diphosphine Ligands at the Platinum Atom

Abstract

Two different synthetic methods were applied to obtain heteronuclear phenylvinylidene clusters CpReFePt(μ 3 -C=CHPh)(CO) 5 (P-P) (P-P -bis(diphenylphosphino)ethane (1), bis(diphenylphosphino)propane (2)). The compounds were studied by IR and NMR spectroscopy. Their molecular structures were proposed based on IR, NMR spectroscopic data.
