Diaqua­bis(4-methyl­amino­benzoato-κO)bis­(nicotinamide-κN (1))cobalt(II)

The asymmetric unit of the title Co(II) complex, [Co(C(8)H(8)NO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], contains two half complex mol­ecules with similar structures. The Co(II) atoms are each located on an inversion center and each is coordinated by two 4-methyl­amino­benzoate (PMAB), two nicotinamide (NA) ligands and two water mol­ecules in a distorted octa­hedral coordination. The dihedral angles between the carboxyl­ate groups and the adjacent benzene rings are 3.0 (3) and 2.54 (19)°, while the pyridine and benzene rings are oriented at dihedral angles of 67.40 (8) and 66.25 (8)°. In the crystal structure, inter­molecular O—H⋯O and N—H⋯O hydrogen bonds link the mol­ecules into a supra­molecular structure.
