Reaction of [FeCo(CO)7(µ-CHCRH)](R = H or Ph) with dimethylphenylphosphine. Synthesis and structure of [FeCo(CO)4(µ-CO)-(PMe2Ph)2(µ-CHCH2)], an electronically unbalanced iron–cobalt complex

Abstract

The reaction of [FeCo(CO)₇(µ-CHCRH)](R = H or Ph) with PMe₂Ph leads to complexes [FeCo(CO)₆(PMe₂Ph)(µ-CHCPhH)] and [FeCo(CO)₅(PMe₂Ph)₂(µ-CHCRH)]. The disubstituted compounds contain two PMe₂Ph ligands linked to iron and two bridging ligands, carbonyl and vinyl. The structure of [FeCo(CO)₄(µ-CO)(PMe₂Ph)₂(µ-CHCH₂)] has been solved by X-ray diffraction methods.
