Di­aqua­bis­(3-chloro­benzoato-κO)bis­(nicotinamide-κN (1))cobalt(II)

In the title complex, [Co(C(7)H(4)ClO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the Co(II) atom is located on an inversion center and is coordinated by two 3-chloro­benzoate (CB) anions, two nicotinamide (NA) ligands and two water mol­ecules. The four O atoms in the equatorial plane form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl­ate group and the adjacent benzene ring is 9.14 (9)°, while the pyridine and benzene rings are oriented at a dihedral angle of 82.18 (8)°. In the crystal, N—H⋯O and O—H⋯O hydrogen bonds link the mol­ecules into a two-dimensional network lying parallel to (101). π–π stacking between parallel pyridine rings of adjacent mol­ecules [centroid–centroid distance = 3.7765 (8) Å] further stabilizes the crystal structure.
