A series of new vanadyl (VO(IV)) complexes were created using tetradentate N2O2 Schiff base ligands, characterized through various analytical techniques like FT-IR and UV-vis, with one complex studied in detail using X-ray crystallography.
The electrochemical analysis showcased a correlation between oxidation potentials and the electron-withdrawing properties of substituents on the Schiff base ligands, with a specific trend observed.
Thermal decomposition of these complexes was analyzed, revealing first-order kinetics and indicating good thermal stability, while unexpected formation of a new vanadium oxide compound during one synthesis was also documented.
