摘　　要：合成了3:2型固体配合物[Ln(NO_3)_3]_3(DB30C10)_2·nH_2O(Ln=La、Ce、Nd、Eu时,n=6;Ln=Sm时,n=5:Ln=Cd时,n=4)。研究了冠醚及其配合物的红外光谱、紫外光谱及其热稳定性,讨论了配体、硝酸盐及配合物的荧光性能。乙腈中的电导测定结果表明配合物均为非电解质。Six new 3: 2 solid coordination compounds of rare earth nitrates with dibenzo-30-crown-10(DB30C10) having composition of [Ln (NO_3)_3]_3 (DB30ClO)_2·nH_2O (Ln =La, Ce,Nd, Eu, n=6; Ln = Sm, n = 5; Ln = Gd, n = 4) have been synthesized in nonaqueous solventsand characterized by elemental analyses, infrared (IR), electronic spectra (UV) and fluores-cence spectra, as well as thermogravimetric (TG) and differential thermal analyses (DTA).All these complexes are proved to be nonelectrolytes by conductance measurement inacetonitrile solution.
