Abstract: In the title compound, [Co(C₅H₃O₄)₂(H₂O)₂]·2C₃H₇NO, the octahedrally coordinated Co^II atom lies on an inversion centre. The equatorial plane of the octahedron comprises two bidentate 1H-imidazole-4,5-dicarboxylate monoanions, coordinated through the N-3 atoms, and one carboxylate O atom, with two water molecules in the axial coordination sites. A one-dimensional chain structure is formed by intermolecular hydrogen bonds in the equatorial plane, between the uncoordinated N atom in the imidazole ring and an uncoordinated carboxyl O atom. The two O atoms of the coordinated water molecules in each chain are engaged in two hydrogen bonds with the uncoordinated carboxyl O atoms of two adjacent chains, forming a two-dimensional network structure.
