镧系元素六氟磷酸盐二乙基亚砜配合物的合成及其表征

SYNTHESIS AND PROPERTIES OF DIETHYL SULFOXIDE COMPLEXES OF LANTHANIDE HEXAFLUOROPHOSPHATES

本文在无水甲醇溶剂中合成了十五个新的镧系元素二乙基亚砜配合物,并对其进行了组成分析、X射线粉末衍射、红外光谱、光电子能谱、摩尔电导测定,确定其化学结构式为Ln(DES-O)_n(PF_6)_3〔Ln=La,n=7.5;Ln=Ce-Lu.Pm除外,Y,n=7〕。

The synthesis of the fifteen diethyl sulfoxide complexes of crytalline lan- thanide hexafluorophosphate in methyl is reported in this paper. All of the complexes were studied by means of elemental analysis, x-ray powder pattens, Infrared spectra, x-ray photoelectron spectrascopy and conductance measurement. The complexes of the general for mula 〔Ln(DESO)n〕 (PF6)3 〔where Ln=La, n=7.5; Ln=Ce-Lu. Y, n=7, except Pm〕have been confirmed. PF6 is present in the complexes as a non-coordinating anion.
