在严格无水的CH（2）Cl（2）溶液中，用[GeF（4）（MeCN）（2）]或[SnF（4）（MeCN）（2）]分别与硫醚配体反应，制备了硬刘易斯酸GeF（4）和SnF（4）的第一种硫醚配合物。分离的化合物通过光谱（IR、（1）H和（19）F{（1）H} NMR）和微量分析表征。四个代表性实例[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}]的晶体结构显示具有螯合硫醚的扭曲八面体加合物以及弱的二级Ge-S和Sn-S键。这些化合物是首次报道的硫醚配合物与任何主族金属/准金属氟化物受体的例子。
The first thioether complexes of the hard Lewis acidic GeF(4) and SnF(4) have been prepared by reaction of [GeF(4)(MeCN)(2)] or [SnF(4)(MeCN)(2)] respectively with the thioether ligand in rigorously anhydrous CH(2)Cl(2) solution. The isolated compounds were characterised spectroscopically (IR, (1)H and (19)F{(1)H} NMR) and by microanalyses. Crystal structures of four representative examples, [GeF(4){MeS(CH(2))(2)SMe}], [GeF(4){EtS(CH(2))(2)SEt}], [SnF(4){EtS(CH(2))(2)SEt}] and [SnF(4){(i)PrS(CH(2))(2)S(i)Pr}], 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 fluoride acceptor.
