Di-μ-chlorido-bis­(chlorido{2,2′-[3-(1H-imidazol-4-ylmeth­yl)-3-aza­pentane-1,5-di­yl]diphthalimide}copper(II))

The centrosymmetric dinuclear Cu(II) complex, [Cu(2)Cl(4)(C(24)H(21)N(5)O(4))(2)], was synthesized by the reaction of CuCl(2)·2H(2)O with the tripodal ligand 2,2′-[3-(1H-imid­azol-4-ylmeth­yl)-3-aza­pentane-1,5-di­yl]diphthalimide (L). Each of the Cu(II) ions is coordinated by two N atoms from the ligand, two bridging Cl atoms and one terminal Cl atom. The Cu(II) coordination can be best be described as a transition state between four- and five-coordination, since one of the bridging Cl atoms has a much longer Cu—Cl bond distance [2.7069 (13) Å] than the other [2.2630 (12) Å]. In addition, the Cu⋯Cu distance is 3.622 (1) Å. The three-dimensional structrure is generated by N—H⋯O, C—H⋯O and C—H⋯Cl hydrogen bonds and π–π inter­actions [centroid–centroid distances = 3.658 (4) and 4.020 (4) Å].
