Using appropriate organotin chloride salts and a ligand called 2-[(2,3-dimethylphenyl) amino] benzoic acid (DMPAB), a condensation procedure produced novel complexes such as triphenyltin, dimethyl, diphenyl, and dibutyl-tin. For difficult identification, a variety of analytical methods were used, including elemental analysis, carbon and proton magnetic resonance, and infrared spectra. The agar ditch method was used to assess the antibacterial effectiveness against Staphylococcus aureus and Escherichia coli. When compared to the molecule generated from the ligand, the complexes showed more inhibitory action. Among the complexes tested, the dimethyltin carboxylate complex showed the strongest antibacterial action against Staphylococcus aureus and Escherichia coli. [ABSTRACT FROM AUTHOR]

4-Sulfosalicylic acid (SSA) was used as a ligand to prepare new triphenyltin and dimethyl-tin complexes by condensation with the corresponding organotin chloride salts. The complexes were identified by different techniques, such as infrared spectra (tin and proton), magnetic resonance, and elemental analyses. The 119Sn-NMR was studied to determine the prepared complexes' geometrical shape. Two methods examined the antioxidant activity of (SSA) and prepared complexes; Free radical scavenging activity (DPPH) and CUPRRAC methods. Tri and di-tin complexes gave high percentage inhibition than ligands with both methods due to tin moiety; the triphenyltin carboxylate complex was the best compared with the others. Also, antibacterial activity was assessed by using the agar ditch method against (Escherichia coli) and (Staphylococcus aureus) bacteria. The complexes gave high activity in inhibition than the ligand derived. Also Triphenyltin carboxylate complex showed higher antibacterial activity than the dimethyltin complex against two types of bacteria (Escherichia coli) and (Staphylococcus aureus).
