The Reactivity of [Zn2Cp*2]: Trapping Monovalent {.ZnZnCp*} in the Metal‐Rich Compounds [(Pd,Pt)(GaCp*)a(ZnCp*)4−a(ZnZnCp*)4−a] (a=0, 2)

Inseparable zinc pair: The reaction of homoleptic {GaCp*}‐containing compounds [M(GaCp*)4] (M=Pd, Pt; Cp*=Me5C5) with [Zn2Cp*2] leads to the formation of [M(GaCp*)2(ZnCp*)2(ZnZnCp*)2] (see picture: C gray, Ga yellow, Zn green, Pd blue) and [M(ZnCp*)4(ZnZnCp*)4]. Both molecules involve the novel zinc ligand system {ZnZnCp*}, which contains an intact ZnZn bond.
