Popis: The asymmetric unit of the title complex, [Co(C14H11N2O2)2Cl(H2O)]·2H2O or [Co(dpgH)2Cl(H2O)]·2H2O, where dpgH− is diphenyl glyoximate, consists of one-half of a [Co(dpgH)2Cl(H2O)] complex and one solvent water molecule. The complex is completed through inversion symmetry, with the CoIII atom situated at the centre of symmetry. The coordination geometry around the CoIII atom is distorted octahedral with the four N atoms of the two dpgH− ligands forming an approximate square plane with N—Co—N bite angles of 81.13 (14) and 98.87 (14)°. The Cl− ligand and the water molecule are disordered in a 1:1 ratio and are in the axial positions, almost perpendicular to the plane of the glyoximate ligands [O—Co—Cl = 175.3 (10)°]. The two glyoximate ligands are linked by strong intramolecular O—H...O hydrogen bonds. In addition, O—H...O interactions involving the solvent water molecules and O—H...N hydrogen-bonding interactions are also observed. The solvent water molecule is disordered over five positions with different occupancies.
