摘要
The molecule of the title Cu-II complex, [Cu(C7H4ClO2)(2)(C6H6N2O)(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 CuN2O4 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)degrees, while the two benzene rings and the two pyridine rings are oriented at dihedral angles of 52.20 (8) and 1.56 (6)degrees. In the crystal, N-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds link the molecules into a three-dimensional network. The pi-pi contact between the benzene rings [centroid-centroid distance = 3.982 (2) angstrom] may further stabilize the crystal structure.
