The Co atom in the title compound, [Co(C6H5N2O4)2(H2O)2], is located on an inversion centre and exhibits a distorted octahedral geometry. It is trans coordinated by two N, O-bidentate 5-carboxy-2-methyl-1 H-imidazole-4-carboxylate monoanionic ligands with two water molecules in the axial positions. Each ligand is stabilized by a strong, almost symmetrical, hydrogen bond. Intermolecular N—H...O hydrogen bonds link the molecules into layers, which are further linked into a three-dimensional supramolecular framework through O—H...O hydrogen-bonding interactions involving the water molecules.

In the title compound, [Cd(C6H7N2O5)2], the Cd atom lies on an inversion center and has a slightly distorted octa­hedral geometry. The equatorial plane contains two bidentate 5-carb­oxy-2-methyl-1 H-imidazole-4-carboxyl­ate monoanionic ligands. Two coordinated water mol­ecules occupy the axial sites. Inter­molecular N—H⋯O hydrogen bonds link the mol­ecules into chains, which are further connected by inter­molecular O—H⋯O hydrogen bonds, resulting in a three-dimensional supra­molecular framework.
