Özet

• Abstract: The oxovanadium(IV) template was formed with the reaction between vanadyl sulfate pentahydrate, 2-hydroxybenzophenone-S-allylthiosemicarbazone, and 3-methoxysalicylaldehyde. The synthesized template complex, along with the starting ligand, was subjected to UV-Vis, FTIR, ESI-mass, and magnetic measurement. The square pyramidal structure was proven with the single-crystal X-ray diffraction method. Stronger crystals were formed with π- π interactions, which was also supported by the corresponding peak in the mass spectrum. Electrochemical measurements was performed using a conventional three-electrode cell with cyclic voltammetry (CV) method. CV results show that complex 2 gives one-electron reduction (VIVO –VIIIO) couple and one-electron oxidation (VIVO –VVO) couple at the
• vanadium center. The total antioxidant capacity of the template compound and the starting ligand was performed by the CUPRAC method, yielding that the complex was more potent than the control compound, ascorbic acid.
