In the title compound, [Co(C4H3N2O2)2(H2O)2], the CoII ion is located on a twofold rotation axis and shows a distorted octahedral coordination configuration, defined by two N,O-bidentate 1H-imidazole-4-carboxylate ligands in the equatorial plane and two water molecules in the axial positions. In the crystal, O—H
O and N—HO hydrogen bonds link the molecules into a three-dimensional supramolecular network. π–π stacking interactions between the imidazole rings [centroid–centroid distances = 3.4914 (15) and 3.6167 (15) Å] further stabilize the crystal structure.
