Molecular cut-outs of Mo/Zn hume-rothery phases: Synthesis and structure of [{Mo(CO)<inf>4</inf>}<inf>4</inf>(Zn)<inf>6</inf>(μ-ZnCp*) <inf>4</inf>]

Abstract:

Zinc in the middle: The reaction of [Mo-(GaCp*)2(CO) 4] and Zn(CH3)2 results in the cluster [{Mo(CO)4}4(Zn)6(μ-ZnCp*) 4] (see picture), the first metalloid cluster with naked zinc atoms as cluster elements. This complex indeed represents a molecular cut-out of a Mo/Zn alloy, which is not only substantiated by similar interatomic distances but by direct comparison of coordination environments of the metal atoms.
