Conversion of a bridged vinylalkylidene complex into cluster complexes of cobalt, iron, and manganese: X-ray crystal structures of [Fe3(CO)6(µ-CO)2(µ3-CMe)(η-C5H5)] and [FeCo3(CO)7(µ-CO)2(µ4-CCH2)(η-C5H5)]

Abstract

The compound [Fe₂(CO)₂(µ-CO)(µ-CCH₂)-(η-C₅H₅)₂] reacts with [Fe₂(CO)₉], [H₃Mn₃(CO)₁₂], [Co₂(CO)₈], or [Co₄(CO)₁₂] to afford, respectively, [Fe₃(CO)₆(µ-CO)₂(µ₃-CMe)(η-C₅H₅)], [Fe₂Mn(CO)₃(µ-CO)₃-(µ₃-CMe)(η-C₅H₅)₂], and [Co₃Fe(CO)₇(µ-CO)₂(µ₄-CCH₂)-(η-C₅H₅)], the structures of the Fe₃ and Co₃Fe clusters benig established by X-ray diffraction studies.
