Abstract
Two different synthetic methods were applied to obtain heteronuclear phenylvinylidene clusters CpReFePt(μ3-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.
