Triphenyltinbenzoate was synthesized using triphenyltinchloride and silver benzoate prepared from sodium benzoate. The structure of the synthetic compound was elucidated by spectral and C, H analysis. The antibacterial activities of the organotin compound were determined against four bacteria namely Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923), Streptococcus pyogenes (clinical isolate) and Pseudomonas aeruginosa (ATCC 27853) in vitro experiment. All the bacteria were inhibited at a concentration of 200 μg/ml and 20 μg/ml in dimethylsulphoxide solution and the minimum inhibitory concentration was found to be same, 7.5 μg/ml for Escherichia coli, Staphylococcus aureus, Streptococcus pyogenes and 10 μg/ml for Pseudomonas aeruginosa.
