Studies of Disulfoxide Complexes of Lanthanide Ⅴ.Lanthanide Perchlorate Complexes with Meso-bis(phenylsulfinyl)ethane

Lanthanide perchlorate complexes with meso-bis（phenylsulfinyl）ethane（meso-BPhSE）of type[LnL3-ClO4]（ClO4）2,where Ln=La～Nd,Sin,Gd～Ho,Tm～Lu,have been prepared and characterized by elementalanalysis,electrical conductance,infrared and electronic spectra,magnetic moment measurement and thermalanalysis.Meso-BPhSE acts as a neutral ligand which combines with lanthanide ion through oxygen atom ofdisulfoxide moieties.In all complexes,except that of Ho,meso-BPhSE does not behave as a complete bidentatechelate but does coordinate,at least partially,as a monodentate ligand.For the Ha complex all meso-BPhSEacts as bidentate ones.

Synthesis and Spectral Properties of Mixed-Ligand Complexes of Lanthanide Perchlorate with Bis-(phenylsulfinyl)ethane and Organic Lewis Bases

Six lanthanide complexes with bis(phenylsulfinyl)ethane(bphse) and organic bases(phen: 1,10 phenanthroline and bipy: 2,2'-bipyridine) were synthesized and characterized by elemental analysis, conductance and spectral (IR, UV Visible) data. The complexes were Ln(bphse) 2(bipy)(ClO 4) 3· n H 2O and Ln 2(bphse) 3(phen) 2(ClO 4) 6·H 2O(where Ln=Nd, Eu and Gd; n =0～2). IR spectral data confirmed that the lanthanide ions were coordinated by oxygen atoms from bphse and nitrogen atoms from phen or bipy. Exitation and emission spectra of Eu complexes were measured and discussed.

钇的双亚砜配合物的合成及表征

具有双齿配位基团的双亚砜作为金属离子的萃取剂已引起人们的注意,双亚砜的过渡金属和镧系元素的配合物已有较多研究,而钇的双亚砜配合物却报导甚少。为扩展双亚砜对金属离子的配位作用的研究,和为双亚砜作为钇与其它稀土元素分离的萃取剂提供基础数据,本文合成了钇的高氯酸盐,硝酸盐和氯化物与高、低熔点的双(正—辛基亚砜)乙烷(α、β—BOSE)和双(苯基亚砜)乙烷(αβ—BPhSE)的十二个配合物,并对其性质进行了研究。
