Abstract: The title compound was synthesized and characterized by elemental analysis, thermo-analy-sis(TG-DTA), 1R and X-ray diffraction analysis.The carystal belongs to triclinic system with a=9. 782(2)Å,6=9. 978(2)Å, c=9. 562(2)Å, α=91.62(2)°, β=111. 09(1)°, γ=104. 75(2)°,V=834. 7A3,Z=1,Dc=1. 52 g·cm-3,Dm=1.51 g·cm-3,M=764. 22, F(000)=387e and the space group is P1.The structure was solved by patterson method and refined by least squares method to final R=0. 045 for 2491 reflections. Cu (Ⅱ) is hexacoordinated and lies on the plane formed by four oxygen atoms, two quinoline molecules with Cu(Ⅱ) form the trans-bis-quinoline addut. The plane CuO4is almost perpendicular to the quinoline ring, the angle between the planes is 93. 8°.
