摘要: 合成了稀土高氯酸盐分别与一缩二乙二醇二甲醚(EO2Me2)和一缩二乙二醇-二-(邻甲氧基苯基)醚[EO2(MeOP)2]形成的两系列17种新的配合物,经元素分析、IR、NMR表征,确定配合物组成为Ln3(ClO4)9(EO2Me2)5·18H2O(Ln=La,Pr,Nd)和Ln(ClO4)3EO2Me2·8H2O(Ln=Sm,Eu,Gd,Tb,Dy,Ho,Er,Yb,Y)及Ln(ClO4)3EO2(MeOP)2·6H2O(Ln=La,Pr,Nd,Eu,Gd).讨论了它们的NMR及光谱等性质,研究了不同端基直链聚醚对配位作用的影响。

Abstract: Seventeen new complexes of rare earth perchlorates with diethylene glycol dimethyl ether (EO2Me2) and diethylene glycol bis(o-methoxy phenyl) ether [EO2 (MeOP)2] were synthesized and characterized by elemental analysis, molar conductivity, XRD, IR, thermal analysis and 1H NMR.The compositions can be formulated as Ln3(ClO4)9·(EO2Me2)5·18H2O(Ln = La, Pr, Nd),Ln(ClO4)3 .EO2Me2·8H2O (Ln=Sm-Er, Yb.Y) and Ln(ClO4)3EO2 (MeOP)2·6H2O (Ln = La,Pr, Nd,Eu,Gd).Their properties, especially NMRand IRspectra, were investigated.The effect of terminal group of acyclic glycol on the compositions and properties of the complexes studied was discussed in detail.Some significant results were obtained.
