| Abstract: | Fifteen lanthanide, including Eu (Ⅱ), complexes of 18-membered hexaaza macrocyclic ligands and one free macrocyclic compound have been prepared by template reactions. Their compositions and structures were ascertained by elemental analyses, infrared spectra, electrical conductance measurements and DTA-TG analyses. The stability of these solid complexes and their characters in aqueous solution have been studied as well. The results indicated that the complexations of lanthanide ions with 18-membered hexaaza macrocyclic ligands are very stable, but the replacement of the ligands other than macrocycle is taken place easily. |
