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)°, 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 ?-? contact between the benzene rings [centroid-centroid distance = 3.982 (2) Å] may further stabilize the crystal structure.eninfo:eu-repo/semantics/openAccessArticle697m356m35710.1107/S1600536813014694N/A
