摘要
在非水介质中合成了5种轻稀土高氯酸盐与配体二甘双酰氮甲基苯胺形成的固体配合物,通式为[Ln(L)2(H2O)2](ClO4)3(Ln=La,Pr,Nd,Sm或Eu)。用元素分析、摩尔电导、红外光谱、核磁共振和TG DTA分析对这些配合物进行了表征。结果表明,在这些新配合物中,配体L表现为三齿配位行为。
Lanthanide perchlorate complexes with the ligand N, N′-dimethyl-N, N′-diphenyl-3-oxapatanediamide,DMDPhOPDA,(L) have been prepared in non-aqueous media. These complexes with general formula [Ln(L)_2(H_2O)_2](ClO_4)_3 (Ln = La, Pr, Nd, Sm, Eu), have been characterized by elemental analysis, conductivity measurement, IR spectra, ~1H NMR spectra, and TG-DTA techniques. In all the complexes, the ligand (L) shows tridentate behavior.
