Diaqua­bis­(1H-imidazole-4-carboxyl­ato-κ(2) N (3),O)cobalt(II)

In the title compound, [Co(C(4)H(3)N(2)O(2))(2)(H(2)O)(2)], the Co(II) 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—H⋯O 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.
