A new CuII complex with a diazamesocyclic ligand based on 1,4-diazacycloheptane (DACH) and functionalized with two additional quinoline donor groups, namely N,N-bis(quinolin-8- ylmethyl)-1,4-diazacycloheptane L, has been synthesized and characterized. X-ray diffraction analysis at room temperature indicates that the title complex [CuLCl](ClO4) 1 (C25H26Cl2N4O4Cu, Mr = 580.94) crystallizes in triclinic, space group P1 with a = 9.589(3), b = 10.857(4), c = 12.724(5) ? a = 98.168(7), b = 106.945(7), g = 101.248(7), V = 1214.6(8) 3, Z = 2, Dc = 1.588 g/cm3, F(000) = 598 and m(MoKa) = 1.161 mm-1. The final R = 0.0479 and wR = 0.0985 with 4267 independent reflections. In the mononuclear CuII complex, the CuII center is pentacoordinated to four nitrogen donors of the ligand and one axial chloride anion, taking a coordination sphere in the midst of the ideal square- pyramid and trigonal bipyramid.
