| 摘 要： | 在乙腈介质中制得了2:1型固态配合物Ln(NO_3)_3]_2·DB24C8.2H_2O(Ln=La、Pr)和3:2型固态配合物Ln(NO_3)_3]_3(DB24C8)_2·3H_2O(Ln=Nd,Sm,Eu)。研究了冠醚及其配合物的红外光谱、紫外光谱、热稳定性及X—射线粉末衍射等性质,观察了它们在常见有机溶剂中的溶解情况,在乙腈中的电导测定结果表明这些配合物均为非电解质。

| Abstract: | The 2:1 solid complexesLn(NO3)3]2-DB24C8 2H2O(Ln = La,Pr)and the 3:2solid complexesLn(NO3)3]3 (DB24C8)2 3H2O(Ln = Nd, Sm, Eu) have been synthesized in acetonitrile medium and characterized by elemental analyses, IR and UV spectra, thermogravimetric(TG)and differential thermal analyses (DTA), as well as X-ray powder diffraction. The solubility behaviour of the complexes in some organic solvents are observed. Furthermore, all these complexes are proved to be nonelectrolytes by conductance measurement in acetonitrile solution. |
