spectroscopically (IR, 1H and 19F1H} NMR) and by microanalyses. Crystal structures of four representative examples, [GeF4MeS(CH2)2SMe}], [GeF4EtS(CH2)2SEt}], [SnF4EtS(CH2)2SEt}] and [SnF4iPrS(CH2)2SiPr}], reveal distorted octahedral adducts with chelating thioethers, and weak, secondary Ge–S and Sn–S bonds. These compounds are the first reported examples of thioether complexes with any main group metal/metalloid
通过[GeF 4(MeCN)2 ]或[SnF 4(MeCN)2 ]分别与硫醚反应制备了硬路易斯酸性GeF 4和SnF 4的第一硫醚配合物。配体在无水CH 2 Cl 2溶液中溶解。分离出的化合物通过光谱表征(红外,1 H和19 F 1 H}核磁共振)和微量分析。四个代表性实例的晶体结构,[GeF 4 MeS(CH 2)2 SMe}],[GeF 4 EtS(CH 2)2 SEt}],[SnF 4 EtS(CH 2)2 SEt}]和[ SnF 4 i PrS(CH 2)2 S i Pr}],显示扭曲的八面体加合物,具有螯合的硫醚,以及弱的次级Ge-S和Sn-S键。这些化合物是硫醚与任何主族金属/准金属氟化物受体配合物的首次报道实例。
