Article abstract of DOI:10.1107/S0108270198013614

In the title compound, [Co(C₆H₇N₂O₃)₂], the Co^II ion has a slightly distorted octahedral coordination geometry. 2-Hydroxy-3-(1H-imidazol-4-yl)propanoic acid acts as a bidentate ligand. Two carboxylate O atoms and two hydroxyl O atoms are coordinated cis to each other and form the equatorial plane, and two imidazole N atoms are coordinated in axial positions. The molecules are held together by an intermolecular hydrogen-bonding network involving the carboxylate, imino and hydroxyl groups.
