Diaqua-bis-{5-carb-oxy-2-[(1H-1,2,4-triazol-1-yl)meth-yl]-1H-imidazole-4-carboxyl-ato}zinc.


ABSTRACT: In the title compound, [Zn(C(8)H(6)N(5)O(4))(2)(H(2)O)(2)], the six-coordinate Zn(II) ion, which is located on an inversion center, has a distorted octa-hedral configuration. Each 5-carb-oxy-2-[(1H-1,2,4-triazol-1-yl)meth-yl]-1H-imidazole-4-carboxyl-ate ligand chelates to the Zn(II) ion through a triazole N atom and a carboxyl-ate O atom in the equatorial plane. The coordination sphere is completed by two water mol-ecules in axial positions. There is an intra-molecular O-H?O hydrogen bond in the ligand. In the crystal, mol-ecules are linked via inter-molecular O-H?O, O-H?N and N-H?N hydrogen bonds, forming a three-dimensional structure.
