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α=0.8844(2),b=1.6286(4),c=1.7751(5)nm,V=2.5568(2)nm[3],Z=4,Dx=1.33g.cm[-3],F(000)=1068e,μ=9.2cm[-1](MoKα).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.两个配位平面CuN(1)O(1)禁CuN(2)O(2)之间夹角为39.3度.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.

The crystal and molecular structure of bis[N-(R)-a-methylbenzyl salicylaldiminato]copper(II) complex

The title complex is orthorhombic, space group P212121, with a 0.8844(2), b 1.6286(4), and c 1.7751(5) nm; dc = 1.33 for Z = 4. Final R = 5.8% (Rw = 4.7%) for 2604 reflections. Atomic coordinates are given. The Cu environment of the complex is a distorted tetrahedral conformation. The angle between the plane defined by the N(1)-Cu-O(1) and N(2)-Cu-O(2) groups is ~39.3? The a-methylbenzyl groups point to the same side of the approx. Cu,N(1),O(1),N(2),O(2) ligand plane (cis), and they are roughly perpendicular to the remainder of the mol. and roughly perpendicular to each other.
