近年来已开始研究镧系元素的含氮大环络合物,但仅得到了十八元的六氮大环络合物[1～3],对大环络合物的光谱等性质的研究也较少。作者用模板合成的方法由丙二胺与2,6-二乙酰吡啶在钕盐的模板作用下,缩合得到了新的钕(Ⅲ)的含氮二十元大环络合物:Nd_3(x)_9L_2·4H_2O(x=NO_3~-、ClO_4~-、CNS~-;L=C_(24)4H_(30)N_6;2、8、14、20-四甲基-3、7、15、19、25、26-六氮杂三环[19、3、1、1~(9,13)]廿六碳-1(24)、2、7、9(26)、10、
In recent years, the nitrogen-containing macrocyclic complexes of lanthanides have been studied, but only 18-membered hexaazaisowurtzitane complexes have been obtained [1-3]. The spectroscopic properties of the macrocyclic complexes Also less. The authors synthesized a new 20-membered nitrogen-containing macrocyclic nitrogen-containing complex of neodymium (III) by the template synthesis method from the reaction of propylenediamine and 2,6-diacetylpyridine under the neodymium salt template: Nd 3 ) _9L_2 · 4H_2O (x = NO_3 ~ -, ClO_4 ~ -, CNS ~ -; L = C_ (24) 4H_ (30) N_6; 2,8,14,20-tetramethyl-3,7,15,19 (24), 2,7,9 (26), 10,25,26-hexaazatricyclo [19,3,1,1- (9,13)
