Metal‐rich cluster compounds having novel structures are formed upon reaction of [NiCp′(CO)Br] (Cp′ = methylcyclopentadienyl) with Se(SiMe 3 ) 2 —the 66‐electron cluster 1 is the presumed reactive intermediate involved in the formation of larger clusters. A total of four complexes were isolated by fractional crystallization. All were characterized by X‐ray structure analysis.
