Abstract
18-membered hexadentate N 4O 2 and N 3O 3 Schiff-base polyoxaazamacrocycles derived from 2,6-bis(2-aminophenoxymethyl) pyridine and different organic dicarbonyl compounds are obtained by a template procedure as mononuclear lanthanide(III) complexes. In the absence of the metal salt, macrocycles are not formed. The complexes were characterised by elemental analysis, molar conductivity and mass, UV-V, IR, 1H NMR and 13C NMR spectroscopy.
