氟磺酸盐
氟磺酸盐是氟磺酸的盐,含有SO3F−离子。氟磺酸根可以看作是硫酸氢根的一个羟基被氟取代而成的离子。[1]氟磺酸根离子与金属阳离子形成配合物的倾向较低。由于氟的大小和氧相似,氟磺酸根基本是四面体形的,类似于高氯酸根。它和硫酸氢根 HSO−
4是等电子体。[2] 如果氟磺酸的氢原子被替换成有机基团,就会形成氟磺酸酯。

在溶液中,氟磺酸根会完全电离。这个离子的体积为 47.8 cm3/mol。[3]大部分金属和季铵盐都可以形成氟磺酸盐。[3]氟磺酸盐可以由金属氯化物和无水氟磺酸反应而成,并放出氯化氢。复分解反应制备法包括金属硫酸盐和氟磺酸钡的反应,或是金属氯化物和氟磺酸银的反应,会留下沉淀。[3]
氟磺酸根的配位性很弱,且难以氧化。它在历史上作为很重要的非配位阴离子模型。然而,到了21世纪,氟硫酸盐在这种用途中被BARF取代了。[2]
很多二元氟磺酸盐是已知的。非金属氟磺酸盐包括卤素和氙的氟磺酸盐。[2]一些三元氟磺酸盐也是已知的,包括 Cs[Sb(SO3F)6]、Cs[Au(SO3F)4]和 Cs2[Pt(SO3F)6][2]。
相关的离子化合物有氟代硒酸盐 SeO3F− 和氟代亚硫酸盐 SO2F−。[4]氟化硫酸盐则是另外一类化合物,它们的氟离子没有和硫酸根连接。
reederite-(Y)是一种含有氟磺酸根的天然矿物。它是一种混合阴离子化合物,其中也存在着碳酸根和氯离子。[5]
