Abstract: The title complex, [Cu₂(C₇H₆NO₂)₂(C₁₂H₈N₂)₂(H₂O)₂]·2C₇H₇NO₂·2H₂O, consists of a dinuclear [Cu₂(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 CuCu separation is 3.109 (2) Å. A twofold axis passes through the mid-point of the CuCu vector.
