摘要
用X射线衍射法测定标题化合物的晶体结构.晶体空间群为P1,Cu(Ⅱ)与2个4,4,4-三氟-1-(2-噻吩基)丁二酮-1,3中的4个氧原子组成正方形,在正方形的轴向上。2个喹啉分子的氮原子与Cu(Ⅱ)配位,形成了六配位的八面体配合物.研究了配合物的热谱、红外光谱.
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) A ,6 = 9. 978(2) A , c = 9. 562(2) A , 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 CuO4 is almost perpendicular to the quinoline ring, the angle between the planes is 93. 8°.
