Abstract

In the title compound, [Zn(C4H3N2O2)2(H2O)2], the ZnII ion is situated on a twofold rotation axis and exhibits a distorted octa­hedral coordination configuration. The equatorial plane contains two cis-oriented bidentate 1H-imidazole-4-carboxyl­ate ligands and the axial positions are occupied by two coordinated water mol­ecules. In the crystal structure, inter­molecular O—H⋯O and N—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional supra­molecular network. There are π–π inter­actions between the imidazole rings, with a centroid-to-centroid distance of 3.504 (3) Å
