Synthesis, characterization and antibacterial screening activity of dibutyltin(IV) and triphenyltin(IV) complexes derivatives of 2,4-dinitrobenzoic and 3,5-dinitrobenzoic acids

Abstract

In this work, five organotin(IV) carboxylate derivatives of 2,4-dinitrobenzoic and 3,5-dinitrobenzoic acids have been successfully synthesized and characterized quantitatively and qualitatively. Results of the spectroscopy studies indicated that the coordination took place via oxygen atoms from the carboxylate anions to the tin atom moieties. From the NMR study, toluene molecule was presented in complexes 3 and 4 which have been clarified and identified. From the preliminary in vitro antibacterial screening study, all the complexes showed some moderate and selective activity against the tested bacterial strains.
