Bis(3-chloro­benzoato-κ(2) O,O′)bis­(nicotinamide-κN)copper(II)

The mol­ecule of the title Cu(II) complex, [Cu(C(7)H(4)ClO(2))(2)(C(6)H(6)N(2)O)(2)], contains two 3-chloro­benzoate (CB) and two nicotinamide (NA) ligands; the CB act as bidentate ligands, while the NA are monodentate ligands. The resulting CuN(2)O(4) coordination polyhedron is a considerably disto...

Sumario:The mol­ecule of the title Cu(II) complex, [Cu(C(7)H(4)ClO(2))(2)(C(6)H(6)N(2)O)(2)], contains two 3-chloro­benzoate (CB) and two nicotinamide (NA) ligands; the CB act as bidentate ligands, while the NA are monodentate ligands. The resulting CuN(2)O(4) coordination polyhedron is a considerably distorted octahedron. The dihedral angles between the carboxyl­ate groups and the adjacent benzene rings are 17.92 (12) and 24.69 (16)°, while the two benzene rings and the two pyridine rings are oriented at dihedral angles of 52.20 (8) and 1.56 (6)°. In the crystal, N—H⋯N and C—H⋯O hydrogen bonds link the mol­ecules into a three–dimensional network. The π–π contact between the benzene rings [centroid–centroid distance = 3.982 (2) Å] may further stabilize the crystal structure.
