摘要： 本文合成了标题18员氮杂大环化合物H2L,通过在水溶液中H2L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(H2L)(NO3)3·nH2O,并对其进行了溶解性、摩尔电导、IR、DTA、TG等表征。

Abstract: The synthesis of a novol 18 membered title compound (H2L) is reported.Lanthanidecomplexes (La through Lu, Pm excluded) with this ligand have been prepared in aqueoussolution by the interaction of H2L with rare earth nitrates.All these complexes crystallizedin microcrystalline powder wth composition of Ln(H2L)·(NO3)3·nH2O, 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.

Key words: hexamethyl-tetraazacyclooctadecane N-acetic acid, rare earth, complexes, synthesis
