Abstract: In the title centrosymmetric binuclear CuII complex, [Cu2(C7H4ClO2)4(C10H14N2O)2], the two CuII cations [CuCu = 2.6314 (4) Å] are bridged by four 3-chlorobenzoate (CB) anions. The four carboxylate O atoms around each CuII cation form a distorted square-planar arrangement, the distorted square-pyramidal coordination geometry being completed by the pyridine N atom of the N,N-diethylnicotinamide (DENA) molecule. The dihedral angle between the benzene ring and the carboxylate group is 4.49 (11)° in one of the independent CB ligands and 12.00 (10)° in the other. The benzene rings of the independent CB ligands are oriented at a dihedral angle of 84.13 (6)°. In the crystal, weak C-HO hydrogen bonds link the binuclear complex molecules into supramolecular chains running along .
