Abstract

The new bimetallic Fe-Ni carbide containing cluster complex, Fe₄Ni(Cp)₂(CO)₁₀(μ₅-C), 4 was afforded by metal-metal exchange and metal cluster rearrangement processes in the reaction of Fe₅(μ₅-C)(CO)₁₅, 1, with NiCp₂ at 80 °C. A minor product Fe₅(Cp)₂(CO)₁₀(μ₅-C), 5, was also obtained from this reaction which contains no nickel and is a di-Cp substituted derivative of 1. Both compounds were characterized by a combination of IR, ¹H NMR, mass spectrometry, elemental and single crystal X-ray diffraction analyses. Compound 4 consists of an open Fe₄Ni(μ₅-C) cluster framework with a carbide ligand where one iron atom bridges a butterfly arrangement of one nickel and three iron atoms.
