title: Bis[6-(1H-benzimidazol-2-yl-κN)pyridine-2-carboxyl-ato-κN,O]cobalt(II) dihydrate.
abstract: In the title compound, [Co(C(13)H(8)N(3)O(2))(2)]·2H(2)O, the Co(II) atom has a distorted octa-hedral environment defined by four N atoms and two O atoms from two 6-(1H-benzimidazol-2-yl)pyridine-2-carboxyl-ate ligands. In the crystal, the complex mol-ecules and uncoordinated water mol-ecules are linked via N-H⋯O and O-H⋯O hydrogen bonds, forming a two-dimensional supra-molecular structure parallel to (010). π-π inter-actions are present between the imidazole, pyridine and benzene rings [centroid-centroid distances = 3.528 (2), 3.592 (2), 3.680 (2) and 3.732 (3) Å].
