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 P-1 with a = 9.589(3), b = 10.857(4), c = 12.724(5) A,α= 98.168(7), β= 106.945(7), γ= 101.248(7)°, V= 1214.6(8) A3, Z= 2, Dc = 1.588 g/cm3, F(000) =598 and μ(MoKα) = 1.161 mm-1. The final R = 0.0479 and wR = 0.0985 with 4267 independent reflections. In the mononuclear CuII complex, the Cu11 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.
