Synthesis, characterization, and antioxidant material activities of organotin (IV) carboxylates with tin-para methoxy benzoic acid

This study compares whether the antioxidant activity of Para Methoxy Benzoic Acid (L) and its organotin complexes has increased or decreased using methods of: 2,2-diphenyl-1-picrylhydrazyl (DPPH) and CUPRAC technique for di and tri-organotin(IV) compounds. The condensation reactions of Tin-Para Methoxy Benzoic Acid as a ligand with di and tri-organotin(IV) compounds yielded four organotin complexes (1–4). Infrared spectroscopy (FTIR), 119Sn nuclear magnetic resonance (NMR), and 1H NMR techniques were utilized to investigate the resultant complexes. Because of the metal moiety, the ensuing organic tin(IV) complexes exhibited stronger antioxidant activity than the ligands produced from it, and compound 3 had higher antioxidant activity than the others.
