Abstract: Two ternary complexes of RE(ClO4)3-DPSO-phen and two binary complexes of RE(ClO4)3-phen have been synthesized (RE=Eu, Tb; DPSO=diphenyl sulfoxide, phen=1,10-phenanthroline). Elemental analysis and TG-DTA studies suggest that the ternary complexes consist of RE(ClO4)3(DPSO)(phen)3·nH2O (n=1, 3) and binary complexes consist of RE(phen)4(ClO4)3. IR spectra studies indicate that the DPSO ligand is bonded with RE(Ⅲ) through oxygen atom in sulfinyl group and phen ligand is bonded to RE(Ⅲ) through nitrogen atom. The molar conductivities measured in the acetonitrile solution indicate that two inorganic anions ClO4- are coordinated and binary complexes are nonelectrolyte. In the fluorescent spectra it was found that the fluorescence emission intensity of the ternary complexes more intensive than that of the binary complexes.
