Abstract Five dinuclear organotin(IV) complexes, R4Sn2La (R = Me, Ph) and R4Sn2Lb (R = Me, Ph and Bu) have been synthesized from reaction of R2SnCl2 with 2,4′- and 2,2′-bis-substituted diphenylamine arylidene hydrazones, H4La and H4Lb, respectively. The synthesized compounds have been investigated by elemental analysis and IR, 1H NMR, and 119Sn NMR spectroscopy. The structures of Me4Sn2Lb and Ph4Sn2Lb have
摘要通过R2SnCl2与2,4'-和2,2'-双取代反应合成了五种双核有机锡(IV)配合物R4Sn2La(R = Me,Ph)和R4Sn2Lb(R = Me,Ph和Bu)二苯胺亚芳基,分别为H4La和H4Lb。合成的化合物已通过元素分析和IR,1H NMR和119Sn NMR光谱进行了研究。Me4Sn2Lb和Ph4Sn2Lb的结构也已通过X射线晶体学证实。结果表明,完全去质子化的双hydr配体提供了两个连续的ONO三齿结构域,它们与烯醇盐形式的两个SnR2部分配位。配合物中的每个锡原子均采用五配位环境。配体和复合物对革兰氏阳性菌(枯草芽孢杆菌和金黄色葡萄球菌)和革兰氏阴性菌(大肠杆菌和铜绿假单胞菌)均没有抗菌活性。然而,发现配体及其甲基复合物均可降解DNA,这一观察结果与分子对接所提示的相互作用方式相适应。
