Complexes of lanthanide(III) ions with 18-membered Schiff-base macrocycles

摘要

18-membered hexadentate N4O2 and N3O3 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, H-1 NMR and C-13 NMR spectroscopy.
