Özet
In the title centrosymmetric binuclear complex, [Cu2(C 8H7O2)4(C6H 6N2O)2], the Cu atoms [Cu⋯Cu = 2.6375 (6) Å] are bridged by four 4-methyl-benzoate (PMB) ligands. The four nearest O atoms around each CuII ion form a distorted square-planar arrangement, and the distorted square-pyramidal coordination is completed by the pyridine N atom of the isonicotinamide (INA) ligand. Each CuII ion is displaced by 0.2633 (1) Å from the plane of the four O atoms, with an average Cu - O distance of 1.974 (2) Å. The dihedral angles between carboxyl-ate groups and the adjacent benzene rings are 7.88 (19) and 9.68 (10)°, while the benzene rings are oriented at a dihedral angle of 85.90 (9)°. The pyridine ring is oriented at dihedral angles of 8.59 (7) and 83.89 (9)° with respect to the benzene rings. In the crystal structure, inter-molecular N - H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π contacts between the benzene rings and between the pyridine and benzene rings, [centroid-centroid distances = 3.563 (2) and 3.484 (2) Å, respectively] may further stabilize the crystal structure.
