[Ge5Ni2(CO)3]2−: the first functionalized cluster of closo-[Ge5]2−†
Abstract
A new functionalized cluster, [Ge5Ni2(CO)3]2−, derived from the closo-[E5]2− (E = Si–Pb) anions which have been known for decades but whose reactivity has rarely been studied, was successfully isolated from the reaction of [Ni(PPh3)2(CO)2] and [Ge5]2− in ethylenediamine (en) solution, and its formation pathway was also investigated.
