Abstract

The first example of ligand protected Cu–Zn clusters is described. Reaction of [CpCu(CN^tBu)] with [Zn₂Cp*₂] yields [(CuCN^tBu)₄(ZnCp*)₄] (1a) and [(CuCN^tBu)₄(ZnCp*)₃(ZnCp)] (1b). According to DFT calculations, the [Cu₄Zn₄] unit fulfils the unified superatom model for cluster valence shell closing.
