Abstract:Phenylcarboxymethyl Sulfoxide, PhSOCH2COOH(LH), complexes of six lanthanide nitrates: Ln2L2(NO3)4*2LH*nH2O(where Ln=La, Ce, Pr, Nd, Sm, Eu) were synthesized. Elemental analyses, molar conductivities, IR, 1HNMR and TG-DTA measurements were used to characterize the complexes. The results show that the ligand(L) is coordinated to metal ions through two oxygen atoms of the carboxyl group and one oxygen atom of the sulfoxide moieties. Neutral ligang (LH)is coordinated to two metal ions through two oxygen atoms of carboxyl group as an asymmetrical bridging bidentate. The fluorescence spectra of Eu3+ complex indicates that there is no inversion symmetry at the site of Eu3+ ion, but the emission intensity of fluorescence is quite good.The solubility of the complexes is very good in water.
Keywords:rare earths  phenylcarboxymethyl sulfoxide  fluorescence spectrum
