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-Aminoantipyrine was used as ligand to prepare new complexes of triphenyltin, di-butyl and dimethyl-tin complexes by condensation reaction 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 antioxidant activity of 4-aminoantipyrine and prepared complexes were studied by two different methods; Free radical scavenging activity DPPH and CUPRRAC methods. Tri and di-tin complexes gave high percentage inhibition than ligand with both methods due to tin moiety, also triphenyltin carboxylate complex was the best compared with the others.
