Abstract: In the title Zn^II complex, [Zn(C₅H₃N₂O₄)₂(H₂O)₂]·C₁₀H₈N₂, the Zn^II atom is octahedrally surrounded by two chelating monodeprotonated 5-carboxy-1H-imidazole-4-carboxylate ligands and two water molecules. Intermolecular O-HO 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-HN 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.
