A dinuclear copper complex:: bis(μ-4-aminobenzoato) bis[aqua(1,10-phenanthroline)copper(II)] dichloride bis(4-aminobenzoic acid) dihydrate

The title complex, [Cu-2(C7H6NO2)(2)(C12H8N2)(2)(H2O)(2)]center dot 2C(7)H(7)NO(2)center dot 2H(2)O, consists of a dinuclear [Cu-2(C7H6NO2)(2)(C12H8N2)(2)(H2O)(2)](2+) cation, two Cl-anions, two 4-aminobenzoic acid molecules and two disordered water molecules (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-aminobenzoic acid ligands and one water O atom. The Cu center dot center dot center dot Cu separation is 3.109 (2) angstrom. A twofold axis passes through the mid-point of the Cu center dot center dot center dot Cu vector.
