摘　　要：本文合成14种镧系高氯酸盐及硝酸盐分别与二甘醇-二-(邻羟基苯基)醚(记为EO_2(HOP)_2,EO=ethylene oxide,HOP为邻羟基苯基)形成的新配合物,确证组成为Ln(ClO_4)_3·EO_2(HOP)_2·nH_2O(Ln:La-Eu,n=10,Ln:Gd,Dy-Tm,Y,n=7),La_3(NO_3)_9·(EO_2(HOP)_2)_2·3H_2O及La(ClO_4)_2·EO_2H(OP)_25H_2O。文中研究了配合物红外,紫外、~1HNMR谱及^(13)C纵向弛豫时间T_1等,并讨论了共存阴离子、溶剂及配体不同端基对成配的影响。Forteen novel complexes of lanthanide perchlorate and nitrate with diethylene glycol di(o-hydroxyphenyl) ether (EO_2(HOP)_2) (EO=ethylene oxide,HOP=o-hydroxyphenyl) have been synthesized and characterized. Compositions of the complexes were comfirmed as Ln·(ClO_4)_3. EO_2(HOP)_2·nH_2O (Ln=La-Eu, n=10; Ln=Gd, Dy-Tm,Y, n=7) ,La_3(NO_3)_9·(EO_2(HOP)_2)_2·3H_2O and La(ClO_4)_3·EO_2H(OP)_2·5H_2O respectively. Some properties of the title coordination compounds were investigated by IR-, UV-Spectra, ~1HNMR and ^(13)C NMR.Effects of eounterion, kinds of solvents and terminal group ligand on eomplexation were also discussed.
