摘要
本文合成了标题18员氮杂大环化合物H_2L,通过在水溶液中H_2L与稀土硝酸盐直接作用合成了14种具有固定组成的镧系配合物Ln(H_2L)(NO_3)_3·nH_2O,并对其进行了溶解性、摩尔电导、IR、DTA。
The synthesis of a novol 18 membered title compound (H_2L) is reported. Lanthanidecomplexes (La through Lu, Pm excluded) with this ligand have been prepared in aqueoussolution by the interaction of H_2L with rare earth nitrates. All these complexes crystallizedin microcrystalline powder wth composition of Ln(H_2L)·(NO_3)_3·nH_2O, independent of themetal to ligand ratio used in the preparation. All these complexes were characterized by ele-mental analysis, thermoanalysis, IR spectra and conductivity measurements.
