摘要
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.
