Abstract

Metal-rich cluster compounds having novel structures are formed upon reaction of [NiCp′(CO)Br] (Cp′ = methylcyclopentadienyl) with Se(SiMe3)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.
