Tetraaquabis(1H-benzimidazole-5,6-dicarboxylato-κN3)cobalt(II) dimethylformamide disolvate dihydrate

In the mononuclear title compound, [Co(C(9)H(4)N(2)O(4))(2)(H(2)O)(4)]·2C(3)H(7)NO·2H(2)O, the Co(II) atom, which lies on a center of inversion, is coordinated by four water mol-ecules and two N atoms from two two symmetry-related 1H-benzimidazole-5,6-dicarboxyl-ate ligands in a distorted octa-hedral geometry. The packing is governed by inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions.
