Synthsis and Characterization of Lanthanide Perchlorate with Phenyl-butyl Sulfoxide Coordination Compounds

本文以稀土高氯酸盐ＲＥ（ＣｌＯ_４）_３ｎＨ_２Ｏ（ＲＥ＝Ｌａ^（３＋）、Ｃｅ^（３＋）、Ｐｒ^（３＋）、Ｎｄ^（３－）、Ｓｍ^（３－）、Ｅｕ（３＋），ｎ＝６～７）与苯丁基亚砜ＰＢＳＯ（Ｃ_６Ｈ_５Ｃ_４Ｈ_９）在无水乙醇体系中合成出六个新配合物，并对配合物进行了元素分析，稀土离子含量测定，配体ＰＢＳＯ含量测定ＣｌＯ_４~－含量测定、ＩＲ谱、导电、ＴＧ－ＤＴＡ分析及Ｘ－射线粉末衍射。确定了配合物的组成为［ＲＥ（ＢＰＳＯ）_７（ＣｌＯ_４）］（ＣｌＯ_４）_２，配位数为８，电解质类型为１：２。

in this paper the six kinds of complexes of lanthanide perchlorate with phenyl-butyl sulfoxide have been synthesized and characterized by elemental analysis , FT-IR ,X-ray powder diffraction, molar conductivities,DTA-TG analysis , From the results of elemental analysis the complex formula is found to be [RE (BPSO)_7 (ClO_4 )] (ClO_4 )_2, (RE=La-Eu, except Pm ). The IR spectra show that the PBSO coordinate with rare earth through oxygen atom and a perchlorate ion coordinates with rare earth ion through oxygen atom too. So the complexes are eight-coordinated.
