چکیده
Tetradentate Schiff bases with a N2O2 donor atom set are well known to coordinate with various metal ions, and this has attracted the interest of many authors1−12. Complexes of Schiff base ligands have been studied for their dioxygen untake and oxidative catalysis. Furthermore, complexes of transition metals(II), which involve derivatives of salicyldhyde and diamine, have received considerable attention. This is because of their potential as catalysts for the insertion of oxygen into an organic substrate15−18. The reaction of tetradentate Schiff bases derived from salicylaldehyde and diamine has been the subject of many studies1−9 . The present study aimed to investigate the reaction of 2 tetradentate Schiff bases derived from the condensation of 4-(benzeneazo) salicylaldehyde with o-phenylenediamine or ethylenediamine with copper, nickel, zinc, cobalt, manganese and cadmium ions. The prepared ligands and complexes were characterized by elemental analysis, molar conductivity measurements, and infrared and electronic spectral data. Two ligands and their Ni(II) and Zn(II) complexes were further identified using H NMR spectra.
