(CH3OCH2CH2CH2)xSnCl4−x, where x = 4 (1), x = 3 (2), x = 2 (3), and x = 1 (4), was prepared. For 3 and 4, which were isolated in the crystalline state, it was shown by X-ray diffraction that the tin atom is coordinated in distorted octahedral and trigonal-bipyramidal geometries, respectively (i.e., the oxygen atoms of the 3-methoxypropyl groups were coordinated to the central tin atom in both cases, forming chelates)
一组四种水溶性(3-甲氧基丙基)锡烷,通式为 (CH3OCH2CH2CH2)xSnCl4−x,其中 x = 4 (1)、x = 3 (2)、x = 2 (3) 和 x = 1 ( 4)、准备。对于在结晶状态下分离的 3 和 4,X 射线衍射表明锡原子分别配位在扭曲的八面体和三角双锥几何中(即 3-甲氧基丙基的氧原子是在两种情况下都与中心锡原子配位,形成螯合物)。对于所有化合物,CDCl3 和 [D6]DMSO 溶液中的结构是根据它们的 13C 和 119Sn NMR 光谱提出的。在CDCl3溶液中,3-甲氧基丙基取代基的中心锡原子和氧原子之间的供体-受体键合程度是根据17O NMR化学位移和3,6J(1H,119Sn)长程耦合常数来评估的。化合物 2 和 3 表现出有希望的体外抗肿瘤和杀锥虫活性。(© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany
