六氟銻酸銅是一種無機化合物,化學式為Cu(SbF6)2。它對水敏感,痕量的水會使其水解,生成H3OSbF6、H3OSb2F11及H3OCu(SbF6)3。[2]它也對OH−敏感。[3]可用作有機反應的催化劑。[4]
製備
[編輯]六氟銻酸銅可由六氟銻酸銀和溴化銅在二氯甲烷(DCM)中反應得到:[5]
- 2 AgSbF6 + CuBr2 → 2 AgBr + Cu(SbF6)2
六氟銻酸銅也可以由氟磺酸銅在五氟化銻中於50 °C發生溶劑分解反應得到:[1]
- Cu(SO3F)2 + 6 SbF5 → Cu(SbF6)2 + 2 Sb2F9SO3F
氟化銅和五氟化銻在無水氟化氫或二氧化硫中反應也能生成六氟銻酸銅:[6]
- CuF2 + 2 SbF5 → Cu(SbF6)2
六氟銻酸銅六水合物可以在丙酮中結晶,經五氧化二磷乾燥得到。[4]
