本文报道标题Schiff碱铜(Ⅱ)配合物的制备和晶体结构的测定。该晶体属正交晶系,空间群为P2_12_12_1,晶胞参数为a=0.8844(2),b=1.6286(4),c=1.7751(5)nm,V=2.5568(2)nm~3,Z=4,D_x=1.33g·cm~(-3),F(000)=1068e,μ=9.2cm~(-1)(MoKa)。用Patterson法和Fourier合成法解出结构,经最小二乘法修正,最终偏离因子R值为5.8%。结构分析结果表明,分子中Cu(Ⅱ)呈畸变的四面体配位。两个配位体平面CuN(1)O(1)和CuN(2)O(2)之间夹角为39.3°。两个水杨醛亚氨基N上的α-甲苄基彼此相互垂直并在CuN(1)O(1)N(2)O(2)的近似平面的同一侧,它们又与各自的水杨醛亚氨基平面几乎垂直。
This paper reports the preparation of the title Schiff base copper (Ⅱ) complex and its crystal structure determination. The crystal belongs to the orthorhombic system with a space group of P2_12_12_1 with cell parameters of a = 0.8844 (2), b = 1.6286 (4), c = 1.7751 (5) nm and V = 2.5568 = 4, D_x = 1.33 g · cm -3, F (000) = 1068e, μ = 9.2 cm -1 (MoKa). The structure was solved by the method of Patterson and Fourier, corrected by the least square method, the final deviation factor R was 5.8%. Structural analysis results show that Cu (Ⅱ) molecules are distorted tetrahedral coordination. The angle between the two ligand planes CuN (1) O (1) and CuN (2) O (2) is 39.3 °. The α-methylbenzyl groups on the two salicylaldimino N are perpendicular to each other and on the same side of the approximate plane of the CuN (1) O (1) N (2) O (2), which are in turn aligned with the respective salicylaldehyde imino plane Almost vertical
