(N-{Amino[(diaminomethylidene)amino]methylidene}-N-methylmethanaminium)tribromidozinc(II)

Abstract

In the title compound, [ZnBr3(C4H12N5)], the ZnII cation is tetrahedrally coordinated by three bromide ions and the (N-{amino[(diaminomethylene)amino]methylene}-N-methylmethanaminium) cation that binds through the central N atom. The complex is of interest as a potential antidiabetic drug of the biguanide family. The crystal structure is stabilized by an extensive series of N—H...Br and C—H...Br hydrogen bonds, which combine to form a three-dimensional structure.
