These compounds were bioassayed to evaluate their bacterial effect against Gram-positive (</span><span lang="EN-US">Staphylococcus aureus and Bacillus subtilis) and Gram-negative (Escherichia coli and Salmonella typhimurium) microorganisms. Dimeric and monomeric compounds were characterized by infrared in solid state. Metallic centers having penta-, hexa-, and heptacoordination were identified by multinuclear NMR (<sup>1</sup>H, <sup>13</sup>C and <sup>119</sup>Sn) in solution. The di- and triorganotin(IV) derivatives were also investigated by conductimetric measurements in methanol, elemental analysis and melting point. The bioassay of these tin(IV) compounds showed that the best resulting activity was against S. aureus for the triphenyltin(IV) phenolic Schiff base derivatives, presenting MICs of 1.1 µM (0.6 </span><span lang="EN-US">m</span><span lang="EN-US">g mL<sup>-1</sup>) and 2.2 µM (1.3 </span><span lang="EN-US">m</span><span lang="EN-US">g mL<sup>-1</sup>).</span></em></p>}, number={5}, journal={The Journal of Engineering and Exact Sciences}, author={da Silva Santos, Ane Francielly and da Silveira Maia, José Roberto}, year={2019}, month={dez.}, pages={0452–0459} }
