Planar pentacoordinate zinc group elements, (M = Zn, Cd, Hg) were computationally found to be at a global minimum in Li 5 M + clusters. The stability of these clusters is due to the presence of multicentric bonds. The central element (Zn, Cd, Hg) in each cluster features a negative oxidation state owing to the in-plane electron donation by the Li 5 + framework. A similar global minimum planar pentacoordinate structure is found in Na 5 Zn + and Na 5 Cd + clusters.
