Bis(1H-imidazole-kN 3)[(2-oxidobenzyl-ideneamino) methanesulfonato-k2 N,O]zinc(II)

The ZnII ion in the title complex, [Zn(C9H4NO4S)(C3H4N2)2], is coordinated by an N atom and an O atom of a deprotonated tridentate Schiff base ligand, and two N atoms from two different imidazole ligands in a distorted tetra-hedral geometry. In the crystal structure, mol-ecules are connected via inter-molecular N - H⋯O hydrogen bonds, forming extended one-dimensional chains along [111]. © International Union of Crystallography 2007.
