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.
本研究成功合成了五种 2,4-二硝基苯甲酸和 3,5-二硝基苯甲酸的有机锡(IV)羧酸盐衍生物,并对其进行了定量和定性分析。光谱研究结果表明,配位是通过羧酸阴离子中的氧原子与锡原子分子进行的。核磁共振研究表明,络合物 3 和 4 中含有甲苯分子,并已对其进行了澄清和鉴定。在初步的体外抗菌筛选研究中,所有复合物都对受试细菌菌株表现出了一定程度的选择性活性。
