Özet
The title Cu II complex, [Cu(C 7H 4BrO2) 2(C 10H 14N 2O) 2(H 2O) 2], contains two 4-bromobenzoate (PBB), two diethylnicotinamide (DENA) monodentate ligands and two water molecules. The four O atoms in the equatorial plane around the Cu II ion form a slightly distorted squareplanar arrangement, while the slightly distorted octahedral coordination is completed by two N atoms of the DENA ligands in the axial positions. Intramolecular O - H⋯O hydrogen bonds link the water molecules to the carboxylate groups. The dihedral angles between the carboxylate groups and the adjacent benzene rings are 3.1 (3) and 3.74 (17)°, while the pyridine rings and the benzene rings are oriented at dihedral angles of 6.81 (10) and 3.38 (12)°. In the crystal, intermolecular O - H⋯O hydrogen bonds link the molecules into double chains along the b axis. C - H⋯O interactions are also observed. π-π contacts between pyridine rings [centroidcentroid distance = 3.485 (2) Å] may further stabilize the crystal structure.
