![]() Use: Antimony (V) fluoride is used mostly as catalyst due to its properties as Lewis acid. The compound can act as a Lewis acid because the antimonium atom has enough free orbitals to accept more electrons. It reacts violently with water.Ĭhemical properties: Antimony (V) fluoride is largely used as catalyst due to it is an acid of Lewis, which means, it is deficient of electrons, thus it can accept easily the electrons available in nucleophiles. Antimony pentafluoride is soluble in sulfur dioxide and potassium fluoride. Its density is 2.99 g/mL and its melting point is 8.3 ✬, meanwhile the boiling point is 149.5 ✬. Physical properties: Antimony pentafluoride is a colorless or whitr oily liquid. Preparation: Antimony pentafluoride is synthesized through the reaction between the antimony pentachloride and hydrogen fluoride:Ī second strategy is the preparation through the fluorination of antimony trifluoride ![]() Occurrence: Antimony (V) fluoride is not found as a natural compound in our planet, it prepared after synthetic methods. Its chemical structure can be written as below, in the common representations used for organic molecules. The geometry of the molecule is a trigonal bipyramide, with a base formed by 3 bonds Sb-F and two axial bonds, which form the vertices. The id formed by a central cation of antimonium Sb +5 and 5 fluoride anions F. Formula and structure: The antimony pentafluoride chemical formula is SbF 5 and its molar mass is 216.74 g mol -1.
