Tetra­kis(μ-3-chloro­benzoato-κ(2) O:O′)bis­[(N,N-di­ethyl­nicotinamide-κN (1))copper(II)]

In the title centrosymmetric binuclear Cu(II) complex, [Cu(2)(C(7)H(4)ClO(2))(4)(C(10)H(14)N(2)O)(2)], the two Cu(II) cations [Cu⋯Cu = 2.6314 (4) Å] are bridged by four 3-chloro­benzoate (CB) anions. The four carboxyl­ate O atoms around each Cu(II) 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—H⋯O hydrogen bonds link the binuclear complex mol­ecules into supra­molecular chains running along [101].
