title: Diaqua-bis-(1H-imidazole-4-carboxyl-ato-κ(2)N(3),O)cobalt(II).
abstract: The title compound, [Co(C(4)H(3)N(2)O(2))(2)(H(2)O)(2)], contains a Co(II) cation on a twofold rotation axis, exhibiting a distorted octa-hedral coordination geometry. The equatorial plane is formed by two N,O-bidentate 1H-imidazole-4-carboxyl-ate ligands and the axial positions are occupied by water mol-ecules. The crystal packing consists of a three-dimensional network stabilized by O-H⋯O and N-H⋯O hydrogen bonds, together with weak π-π inter-actions [centroid-centroid distance = 3.577 (2) Å] between the imidazole rings.
