摘要: 本文合成了题头所示大环配体,并制备了它的十四种镧系元素(La~Lu,Pm除外)固体配合物.用元素分析,DTA-TG,红外光谱以及电导测定等手段研究了这些化合物的组成和性质.基于这些分析结果可建议配合物化学式为Ln(H2L)(NO3)3·nH2O.

Abstract: The synthesis and characterization of a new partially N-alkalated tetraazamacrocyclic ligand 2,2,4,13,13,15-hexamethyl-l,5,12,16-tetraazacyclodocosane-N',N"'-diacetic acids(H2L)are reported. The 14 lanthanide(La through Lu, Pm excluded)complexes with this ligand have been prepared in water solution by the interaction of H2L with the rare earth nitrates. AH these complexes in microcrystalline powder have constant stoichiometry Ln(H2L)(NO3)3·nH2O, irrespective of the metal to ligand ratio used in the preparation. These compounds are characterized by elemental analysis, thermoanalysis, conductivity measurements and IR spetra.
