The chemical name for SbF5 is Antimony pentafluoride.
Antimony pentafluoride (SbF5) is a highly reactive inorganic compound recognized for its remarkable chemical properties. It is a critical substance in advanced chemistry, particularly due to its nature as an exceptionally strong Lewis acid.
Understanding Antimony Pentafluoride
Antimony pentafluoride is characterized by the central antimony atom bonded to five fluorine atoms. Its unique electronic structure makes it a potent electron-pair acceptor, which defines its powerful Lewis acidity. This property allows it to form stable adducts with fluoride ions and other Lewis bases.

Properties and Applications
Antimony pentafluoride exists as a viscous liquid at room temperature and is highly corrosive. Its extreme reactivity makes it a challenging but valuable chemical for specific applications.
- Superacid Systems: One of the most notable applications of antimony pentafluoride is its use in the preparation of superacids. When combined with hydrofluoric acid (HF), it forms fluoroantimonic acid (HSbF6), which is considered one of the strongest known superacids. These superacids are capable of protonating organic compounds that are typically unreactive with conventional acids.
- Fluorination Agent: Due to the presence of highly electronegative fluorine atoms and the high oxidation state of antimony, SbF5 can act as a powerful fluorinating agent in various chemical reactions.
- Oxidizing Agent: In certain contexts, it can also function as a strong oxidizing agent.
- Catalyst: Its Lewis acidity makes it an effective catalyst in certain organic reactions, particularly those involving carbocation formation.
Safety and Handling
Given its highly corrosive and reactive nature, antimony pentafluoride must be handled with extreme caution. It reacts violently with water and many organic compounds. Proper personal protective equipment and a well-ventilated environment are essential when working with this chemical.
