六氟锑酸银是一种配合物,化学式为AgSbF6。可溶于水,具有潮解性[2]它在有机化学中可以用作催化剂[3]

制备

[编辑]

将焦锑酸钠和硝酸银溶于40%的氢氟酸溶液中,于30~50℃反应数小时后,在真空中浓缩,2~10℃冷却,得到六氟锑酸银结晶,抽滤后真空干燥。[4]

此外,氟化银五氟化锑的反应[5]、25℃下氟硼酸银五氟化锑的反应[6]也能得到六氟锑酸银。

AgF + SbF5 → AgSbF6
AgBF4 + 2 SbF5 → AgSb2F11 + BF3
AgBF4 + AgSb2F11 → 2 AgSbF6 + BF3

相关物种

[编辑]

α-六氟锑酸银(I,III)是蓝色的物质,由AgSb2F11F2反应得到:[6]

2 AgSb2F11 + F2 → 2 Ag(SbF6)2

黄色的β-Ag(SbF6)2由Ag(SO3F)2和SbF5反应得到。
