Synthesis of heterotrimetallic (Fe–Co–Ni)–acetylene clusters and X-ray crystal structure of (η5-C5H5) NiCoFe(CO)5(PPh3)(C2Ph2)
Abstract
The heterobimetallic complexes (η5-C5H5) NiCo(CO)3(C2R1R2)[R1= Ph; R2= Ph or Me] react with Fe2(CO)9 to yield the heterotrimetallic clusters (η5-C5H5) NiCoFe(CO)6(C2R1R2); the stereochemistry of a triphenylphosphine derivative, the title compound, has been established by a single-crystal X-ray structure analysis.
