Abstract

original image

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.
