摘要：

A series of novel mixed ligand complexes of yttrium and lanthanide(III) ions with bis(phenylsulphinyl)propane and bipyridyl have been synthesized. The complexes were assigned the formula [Ln(bphsp)(3)(bipy) (ClO4)](ClO4)(2) (bphsp = bis(phenylsulphinyl)propane; bipy = bipyridyl; Ln = La, Pr, Eu, Gd, Tb, Ho, Er, Yb, Y) and [Nd(bphsp)(3)(bipy)(ClO4)](ClO4)(2) . 2H(2)O on the basis of analytical, conductance and spectral (IR, electronic) and magnetic data. In all cases, the lanthanide ion bonds to the sulphoxide moiety via the oxygen atoms and to the bipy via the nitrogen atom. The coordination number of the complexes may be nine. The spectral strength for emission spectrum (D-5(0) --> F-7(2)) of Eu(bphsp)(3)(bipy)(ClO4)(3) was increased by the coordination of bipy.
