摘要： 标题配合物的晶体结构已用X射线衍射确定。它属单斜晶系,空间群为P21/a,晶胞参数为:a=9.824(3Å),b=35.530(9)Å,c=17.552(6)Å,β=98.97(2)°,V=6053(4)Å3,Z=8。结构通过Patterson函数和Fourier技术解出,用块矩阵最小二乘法修正,最后偏差因子R=0.064。该配合物是反式平面配合的加帽结构,平均键长Cu—O=1.870Å,Cu—N=2.007Å,存在两个独立的结晶学分子。

关键词: 晶体结构, 加帽配合物, 空腔

Abstract: The crystal structure of the title complex was determined by X-ray diffraction. It belongs to the monoclinic system, space group is P21/a with cell dimensions a =9. 824(3)Å , b=35. 530(9)ÅA. c=17.552(6)Å,β=98. 97(2)°, V=6053(4)Å3 and Z=8. The structure was analyzed by Patterson and Fourier technique and refined by block-matrix least squares to final residual factor of R = 0. 064. The complex is a trans-planar "capped" structure, with average bond length Cu-O 1.870Å ,Cu-N 2.007Å. There are two crystallographically independent molecules.
