| 摘要: 在乙腈介质中制得了2:1型固态配合物[Ln(NO3)3]2·DB24C8·2H2O(Ln=La、Pr)和3:2型固态配合物[Ln(NO3)3]3(DB24C8)2·3H2O(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 complexes[Ln(NO3)3]2·DB24C8·2H2O(Ln = La,Pr)and the 3:2solid complexes[Ln(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. |
