Abstract
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‐1H‐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.
