Abstract

In the title ZnII complex, [Zn(C5H3N2O4)2(H2O)2]·C10H8N2, the ZnII atom is octa­hedrally surrounded by two chelating monodeprotonated 5‐carb­oxy‐1H‐imidazole‐4‐carboxyl­ate ligands and two water mol­ecules. Inter­molecular O—H⋯O hydrogen‐bonding inter­actions link the mol­ecules in the crystal structure, forming two‐dimensional layers. These layers self‐assemble into a three‐dimensional network through inter­molecular N—H⋯N hydrogen‐bond inter­actions between imidazole N—H and pyridyl N atoms. The Zn atom and the mid‐point of the central C—C bond of the bipyridine are located on inversion centers.
