In the crystal structure of the title compound, [Co(C(13)H(9)N(2)O)(2)]·2C(3)H(7)NO, the Co(II) ion is four-coordinated by two N atoms and two O atoms from two deprotonated 2-(1H-benzimidazol-2-yl)phenol ligands in a distorted tetra-hedral geometry. The dimethyl-formamide solvent mol-ecules are found inside a two-dimensional network structure formed by inter-molecular N-H⋯O hydrogen bonds linking the mol-ecules.
