| The title CoII complex, [Co(C9H10NO 2)2(C6H6N2O)(H 2O)2], contains two 4-dimethyl-amino-benzoate (DMAB) anions, one isonicotinamide (INA) ligand and two coordinated water mol-ecules. One of the DMAB anions acts as a bidentate ligand, while the other is monodentate. The four O atoms in the equatorial plane around the Co atom form a highly distorted square-planar arrangement, while the distorted octa-hedral coordination geometry is completed by the N atom of the INA ligand and the O atom of the second water mol-ecule in the axial positions. An intra-molecular O - H⋯O hydrogen bond between the monodentate-coordinated carboxyl group and a coordinated water mol-ecule results in a six-membered ring with an envelope conformation. The dihedral angles between the carboxyl groups and the adjacent benzene rings are 4.29 (10)° for the monodentate ligand and 2.31 (13)° for the bidentate ligand, while the two benzene rings are oriented at a dihedral angle of 65.02 (5)°. The dihedral angles between the pyridine and benzene rings are 11.21 (5)° for the monodentate ligand and 74.60 (5)° for the bidentate ligand. In the crystal structure, inter-molecular O - H⋯O, O - H⋯N and N - H⋯O hydrogen bonds link the mol-ecules into a supra-molecular structure. |
