Diaqua-bis(4-methyl-amino-benzoato-κO)bis-(nicotinamide-κN)cobalt(II).

ABSTRACT: 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 mol-ecules with similar structures. The Co(II) atoms are each located on an inversion center and each is coordinated by two 4-methyl-amino-benzoate (PMAB), two nicotinamide (NA) ligands and two water mol-ecules in a distorted octa-hedral coordination. The dihedral angles between the carboxyl-ate 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, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into a supra-molecular structure.
