Diaqua­Bis(4-Methyl­Amino­Benzoato-Κo)Bis­(Nicotinamide-Κn 1)Cobalt(Ii)

Abstract

The asymmetric unit of the title CoII complex, [Co(C8H8NO2)2(C6H6N2O)2(H2O)2], contains two half complex mol­ecules with similar structures. The CoII 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.
