Abstract EN
Oxygen absorption-desorption processes for square planar Mn (II), Co (II) and Mn (II) complexes of tetradentate Schiff base ligands in DMF and chloroform solvents were investigated.
The tetradentate Schiff base ligands were obtained by condensation reaction of ethylenediamine with salcyldehyde, o-hydroxyacetophenone or acetylacetone in the molar ratio 1 : 2.
The square planar complexes were prepared by the reaction of the Schiff base ligands with Mn (II) acetate, Co (II) nitrate and Ni (II) nitrate in dry ethanol under nitrogen atmosphere.
The sorption processes were undertaken in the presence and absence of (pyridine) axial-base in 1 : 1 M ratio of (pyridine : metal (II) complexes).
Complexes in DMF indicate significant oxygen affinity than in chloroform solvent.
Cobalt (II) complexes showed significant sorption processes compared to Mn (II) and Ni (II) complexes.
The presence of pyridine axial base clearly increases oxygen affinity.
