• A new ligand and its complexes have been prepared and fully characterized.
• The X-ray diffraction showed that this Schiff-base has monoclinic geometry.
• The pyridine presence in cobalt complex induces an increase of electronic density.
• In the presence of oxygen this compound is more easily oxidizable.
• These products could be investigated in the near future in the field of corrosion.
The present work deals with the synthesis of a new tetradentate Schiff base ligand: di[(4-phenylimino) 4-diethyl salicylaldehyde] ether (H2L) which is used to coordinate copper (II) and cobalt (II) leading to bi- and mono-nuclear complexes [Cu2L (Cl⋅H2O)] and [Co (H2L) Cl2] respectively. In addition to the X-ray diffraction of H2L, these compounds were characterized by the means of elemental and thermal analyses, infrared, electronic and 1H NMR spectra. The cyclic voltammograms of the ligand H2L as well as its complexes in DMF are also discussed.
