镧系与二甘醇-二-(邻羟基苯基)醚配合物的合成与表征
SYNTHESIS AND CHARACTERIZATION OF LANTHANIDE COMPLEXES WITH DIETHYLENE GLYCOL DI(O-HY-DROXYPHENYL) ETHER
【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EO2(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(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及La(ClO4)2·EO2H(OP)25H2O。文中研究了配合物红外,紫外、1HNMR谱及13C纵向弛豫时间T1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。
【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.
