title: cis-Dichloridobis(1,10-phenanthroline)cobalt(II) dimethyl-formamide solvate.
abstract: In the title complex, [CoCl(2)(C(12)H(8)N(2))(2)]·C(3)H(7)NO, which has twofold rotation symmetry, the Co(II) cation is coordinated by two 1,10-phenanthroline (phen) mol-ecules and two chloride ligands in a distorted octa-hedral geometry. In the crystal structure, a cavity is created by six complex mol-ecules connected by C-H⋯π inter-actions and non-classical C-H⋯Cl hydrogen bonds. The cavities are occupied by the disordered dimethyl-formamide solvent mol-ecule. The C and N atoms of the C-N bond in the solvent mol-ecule also lie on a crystallographic twofold rotation axis; the remaining atoms of the solvent are statistically disordered (ratio 0.5:0.5) about this axis.
