摘要
合成了氮杂大环配体C_9H_(22)N_4及其镍的配合物[Ni(C_9H_(22)N_4)](ClO_4)_2。用X-射线衍射方法测定了配合物的晶体结构。晶体属于正交晶系,P2_12_12_1空间群,a=13.069(8),b=14.106(7),C=9.282(4)(?),V=1711.2(?)~3,Z=4,Dc=1.72g/cm^3。配合物中镍为4配位,其配位多面体为扭曲的平面四方形。
A polyazamacrocycle C9H22N4 and its complex were synthesized. The crystal structure of [Ni(C9H22N4)](ClO4)2 was determined by X-ray diffraction method. The crystal is orthorhombic with space group P212121. The unit cell parameters are a=13.009(8), b = 14.106(7), c = 9.282(4)A, V=1711.2A3, Z = 4, Dc=1.72g/cm3. The complex shows a distorted square-planar geometry with four nitrogen atoms of the macrocycle around the central nickel ion. The Ni-N distances fall in the range of 1.885-1.909A with an average of 1.895A.
