A dinuclear copper complex: bis-(μ-4-amino-benzoato)bis-[aqua(1,10-phenanthroline)copper(II)] dichloride bis(4-amino-benzoic acid) dihydrate.

The title complex, [Cu(2)(C(7)H(6)NO(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)]·2C(7)H(7)NO(2)·2H(2)O, consists of a dinuclear [Cu(2)(C(7)H(6)NO(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) cation, two Cl(-) anions, two 4-amino-benzoic acid mol-ecules and two disordered water mol-ecules (site occupancy factors 0.5). The Cu(II) ion adopts a distorted square-pyramidal geometry formed by two N atoms from the 1,10-phenanthroline ligand and two O atoms of the two 4-amino-benzoic acid ligands and one water O atom. The Cu⋯Cu separation is 3.109 (2) Å. A twofold axis passes through the mid-point of the Cu⋯Cu vector.
