Treatment of alpha,omega-dithiols HS(CH(2))(n)()SH, n = 4 or 5, with tris[(triphenylphosphine)aurio]oxonium tetrafluoroborate affords the corresponding S,S,S',S'-tetrakis[(triphenylphosphine)aurio]-alpha,omega-alkanediylbis(sulfonium) bis(tetrafluoroborates) of the type [(Ph(3)P)Au](2)S(CH(2))(n)()S[Au(PPh(3))](2)}(2+)2BF(4)(-). The crystal structure of the species with n = 5 has been determined by single
用四氟硼酸三[(三苯基膦)金]氧鎓处理α,ω-二硫基HS(CH(2))(n)()SH,n = 4或5,得到相应的S,S,S',S'- [((Ph(3)P)Au](2)S(CH(2))(n)()S类型的四[[三苯膦]黄金-α,ω-链烷二基双(s)双(四氟硼酸酯) [Au(PPh(3))](2)}(2+)2BF(4)(-)。n = 5的物质的晶体结构已通过单晶X射线衍射研究确定。在晶格中,未折叠的指示通过末端分叉的二硫ulf中心之间的短双Au-Au接触连接成链。与(外消旋)1,2-二硫代甘油和1,2,3-三硫代甘油的类似反应也产生三核和四核配合物,其中金属原子在硫族元素(ium)中心上分布不同。正如在单晶X射线衍射研究中再次证明的那样,指征HOCH(2)HCS [(Ph(3)P)Au](2)CH(2)S [Au(PPh(3))](2 )}(2+)的二硫代甘油化合物通过分叉末端的听觉性确定的
