摘要： 由三价轻稀土、钇(Ⅲ)和铈(Ⅳ)的硝酸盐分别与2,3,11,12-四苯基-1,4,7,10,13,16-六氧-2,11-十八环二烯反应,合成了相应的六种固体络合物,並进行了元素分析,IR、NMR、TG、DTA、电导及溶解度等性质的研究。

Abstract: Six complexes of the light rare-earth (Ⅲ,Ⅳ)and Yttrium (Ⅲ) nitrates with the title ligand (Ⅲ) have been prepared in methyl-cyanide and benzene. The results of their elemental analyses, infrared spectra, NMR spectra, differential thermal analysis (DTA), thermogravimetry (TG), molar conductance and solubility preliminarily indicated: 1. These complexes are nonelectrolytes in methyl-cyanide; 2. The 1:1 complexes are formed with each Ln(Ⅲ,Ⅳ) ion; 3. Three series have been obtained with formulate Ln(NO3)3·crown ether (n) (Ln = La, Ce, Pr, Nd), Ce(NO3)4·crown ether (1) and Y(NO3)3·crown ether (Ⅲ)·5H2O, and 4. The co-ordination numbers of each Ln ion are about 9-12. The characteristics both thermal stability and solubility of Ln(NO3)3·crown ether (Ⅲ) Ln(NO3)3-dibenzo-18-C-6 and Ln(NO3)3·18-C-s ether were discussed.
