M4H4X: Hydrometals (M = Cu, Ni) containing tetracoordinate planar nonmetals (X = B, C, N, O)

Abstract

The first theoretical evidence for tetracoordinate planar nonmetals hosted at the centers of square hydrometal complexes M4H4X (M = Cu, Ni; X = B, C, N, O; see picture) has been obtained by ab initio calculations. These predictions may open a new branch of chemistry of nonmetal-centered hydrometals with potential applications as catalysts.
