摘要: 研究了钕、钐、铕、钇、镝氯化物与甲基亚砜固体配合物的合成、组成及其红外光谱、差热热重谱、核磁共振等方面的性质,用X射线单晶分析法测定了氯化钕甲基亚砜配合物NdCl3·5DMSO·4H2O的结构。

Abstract: The preparation of a number of complexes of LnCl3(Ln = Nd,Sm,Eu,Gd,Dy, Tb, Er and Yb) with dimethyl sulfoxide is reported.The structures of some of them have been elucidated on the basis of infrared spectra,nmr spectra, thermoana-lysis, X-ray diffraction and chemical analysis.It appears that sulfur is the donor atom in all cases reported.From the results of single crystal X-ray diffraction analysis,it shows that the cell parameters for the species of Nd and Tb are.α= 9.7998, b= 10.1458, C=14.7505 α = 93.0376, β= 100.2652, γ = 99.6542; α= 9.7083, b = 10.1216, c = 14.6725 α = 93.3927, β = 99.8257, γ = 100.1570 respectively.Both of them are triclinic.The structure for Nd species is proposed as a distorted triangle dodecahedron.There are two lanthanide ions, ten DMSO, eight water molecules and six chloride ions in each cell.All the DMSOare coplanar and coordinated with Ln ion through oxygen atom.Among the eight water molecules, six of them are coordinated with center ions, the other two and six chloride ions are in orderly state.
