Bis(μ-3-chloro­benzene-1,2-dicarboxyl­ato-κ(2) O (2):O (2))bis­[diaqua­(5,5′-dimethyl-2,2′-bipyridine-κ(2) N,N′)copper(II)]

In the centrosymmetric binuclear title compound, [Cu(2)(C(8)H(3)ClO(4))(2)(C(12)H(12)N(2))(2)(H(2)O)(4)], the Cu(II) ion is six-coordinated by two N atoms from a 5,5′-dimethyl-2,2′-bipyridine ligand, two bridging O atoms from two 3-chloro­benzene-1,2-dicarboxyl­ate ligands and two water mol­ecules in a distorted octa­hedral geometry. The binuclear complex mol­ecules are linked together by inter­molecular O—H⋯O hydrogen bonds into a layer parallel to (100). The layers are connected by C—H⋯Cl hydrogen bonds. Intra­molecular O—H⋯O hydrogen bonds and π–π inter­actions [centroid–centroid distance = 3.5958 (16) Å] are also present.
