我们合成了〔NH_3-(CH_2)_3-NH_3〕ZnCl_4配合物(简称PDAZn),采用X-射线衍射法研究了该配合物的晶体结构,属于单斜晶系,空间群为P2_1/n,晶胞参数为:a=10.70901(2),b=10.64001(1),c=10.82301(2)A;β=118.4301(1)°;z=4。强度数据由四圆衍射仪收集到独立可观察反射点数目为2047个,采用Mokα辐射(λ=0.71073A)。结构参数的修正采用方块最小二乘法,R=0.041。该配合物与Cu、Mn金属离子构成的配合物的二维片层晶体结构不同,阴离子由单个的四面体MCl_4~(2-)构成。
We have synthesized the [NH_3- (CH_2) _3-NH_3] ZnCl_4 complex (abbreviated as PDAZn). The crystal structure of the complex has been studied by X-ray diffraction and belongs to the monoclinic system. The space group is P2_1 / n, Cell parameters are: a = 10.70901 (2), b = 10.64001 (1), c = 10.82301 (2) A; β = 118.4301 (1) °; z = 4. The intensity data was collected by a four-circular diffractometer with 2047 independent observable reflection points using Mokα radiation (λ = 0.71073A). The structural parameters were corrected using the square least square method, R = 0.041. The complex has a two-dimensional lamellar crystal structure with Cu and Mn metal ions, and the anion is composed of a single tetrahedron MCl 4 2-.
