Fluorosulfonates
Fluorosulfonates (or fluorosulfates ) are a group of chemical compounds that contain the fluorosulfonate anion SO 3 F - . They represent the salts of the fluorosulfonic acid HSO 3 F.
Extraction and presentation
The fluorosulfonate anion can be represented by the reaction of fluorofluorosulfonate and a base .
The reaction of Fluorfluorosulfonat with the iodide - ion results in the formation of the fluorosulfonate ion.

Physical Properties
The fluorosulfonate salts crystallize in various crystal structures and crystal systems . For example, potassium , rubidium and thallium (I) fluorosulfonate have an orthorhombic crystal system . Lithium fluorosulfonate, on the other hand, is monoclinic and sodium fluorosulfonate is hexagonal .
Chemical properties
The fluorosulfonate ion is only weakly coordinated and difficult to oxidize. It is analogous to the perchlorate ClO 4 - structured tetrahedral. In contrast to perchlorate, however, it is not a good oxidizing agent . The alkali metal salts of fluorosulfonic acid are soluble in a variety of protic and aprotic solvents , while the metal complexes are readily soluble in polar solvents.
Examples
- Ammonium fluorosulfonate NH 4 SO 3 F
- Chlorofluorosulfonate ClSO 3 F
- Fluorofluorosulfonate FSO 3 F
- Potassium fluorosulfonate KSO 3 F

- Silver (II) fluorosulfonate Ag (SO 3 F) 2
- Thallium (I) fluorosulfonate TlSO 3 F
- Xenon (II) fluorosulfonate Xe (SO 3 F) 2
