Bis(μ(2)-2-chloro­benzoato-κ(2) O:O′)bis­[(2-chloro­benzoato-κO)(1,10-phenanthroline-κ(2) N:N′)copper(II)] dihydrate

In the title compound, [Cu(2)(C(7)H(4)ClO(2))(4)(C(12)H(8)N(2))(2)]·2H(2)O, the two crystallographically independent dinuclear complex mol­ecules, A and B, have different Cu⋯Cu separations, viz. 3.286 (1) Å in A and 3.451 (1) Å in B. Both independent mol­ecules reside on inversion centres, so the asymmetric unit contains a half-mol­ecule each of A and B and two water mol­ecules. Each Cu atom has a square-pyramidal environment, being coordinated by two O atoms from two bridging 2-chloro­benzoate ligands, one O atom from a monodentate 2-chloro­benzoate ligand and two N atoms from a 1,10-phenanthroline ligand. The water mol­ecules can also be considered as coordinating ligands, which complete the coordination geometry up to distorted octa­hedral with elongated Cu—O distances, viz. 3.024 (3) Å in A and 2.917 (3) Å in B. In the crystal, weak inter­molecular C—H⋯O inter­actions contribute to the consolidation of the crystal packing.
