In the centrosymmetric title compound, [Cu2(C10H8O4)Cl2(C10H8N2)2(H2O)2]·2H2O, the CuII atom is five-coordinated in a distorted square-pyramidal geometry by two N atoms from a chelating 2,2′-bipyridine ligand, one O atom from a 1,4-phenyl­enediacetate ligand, one Cl atom and one water mol­ecule. The 1,4-phenyl­enediacetate ligand, lying on an inversion center, bridges two CuII atoms. In the crystal, O—H⋯O and O—H⋯Cl hydrogen bonds and π–π inter­actions between the pyridine rings [centroid–centroid distance = 3.740 (5) Å] link the complex mol­ecules and uncoordinated water mol­ecules into a three-dimensional network.
