Di-μ-chlorido-bis-(chlorido{2,2'-[3-(1H-imidazol-4-ylmeth-yl)-3-aza-pentane-1,5-di-yl]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-imid-azol-4-ylmeth-yl)-3-aza-pentane-1,5-di-yl]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)†à ] than the other [2.2630†(12)†à ]. In addition, the Cu⋯Cu distance is 3.622†(1)†à . The three-dimensional structrure is generated by N-H⋯O, C-H⋯O and C-H⋯Cl hydrogen bonds and π-π inter-actions [centroid-centroid distances = 3.658†(4) and 4.020†(4)†à ].
