Characterisation of novel macroacyclic hexadentate (N_4O_2 and N_2O_4) Schiff base ligands and their zinc(II), copper(II) and cobalt(II) complexes, with ligands derived from reduction

摘要

The macrocyclic, hexadentate (N_4O_2 and N_2O_4) Schiff base ligands, 1,2-bis(2'-nitrophenoxy)benzene, 1,2-bis (2'-nitrophenoxy)-4-t-butylbenzene), 1,2-bis(2'-aminophenoxy)benzene and 1,2-bis(2'-aminophenoxy)-4-t-butylbenzene have been synthesised, together with macroacyclic hexadentate ligands formed from their reduction. Zinc(II), copper(II) and cobalt(II) complexes of the Schiff base ligands have also been prepared and all compounds have been characterised by spectroscopy and elemental analysis.
