Abstract: Forteen novel complexes of lanthanide perchlorate and nitrate with diethylene glycol di(o-hydroxyphenyl) ether (EO2(HOP)2) (EO=ethylene oxide,HOP=o-hydroxyphenyl) have been synthesized and characterized. Compositions of the complexes were comfirmed as Ln·(ClO4)3. EO2(HOP)2·nH2O (Ln=La-Eu, n=10; Ln=Gd, Dy-Tm,Y, n=7) ,La3(NO3)9·(EO2(HOP)2)2·3H2O and La(ClO4)3·EO2H(OP)2·5H2O respectively. Some properties of the title coordination compounds were investigated by IR-, UV-Spectra, 1HNMR and 13C NMR.Effects of eounterion, kinds of solvents and terminal group ligand on eomplexation were also discussed.

Key words: lanthanide, yttrium, acyclic polyether, complex, NMR
