SbF 3 is used in dyeing and in pottery, to make ceramic enamels and glazes. Other fluorine-containing Lewis acids serve as fluorinating agents in conjunction with hydrogen fluoride. It was once used for the industrial production of freon. The Swarts reaction is generally applied to the synthesis of organofluorine compounds, but experiments have been performed using silanes. This compound can also be produced in bulk. The method involved treatment with antimony trifluoride with chlorine or with antimony pentachloride to give the active species antimony trifluorodichloride (SbCl 2F 3). This application was reported by the Belgian chemist Frédéric Jean Edmond Swarts in 1892, who demonstrated its usefulness for converting chloride compounds to fluorides. It is used as a fluorination reagent in organic chemistry. With fluorine, it is oxidized to give antimony pentafluoride. The compound is a mild Lewis acid, hydrolyzing slowly in water. SbF 3 is prepared by treating antimony trioxide with hydrogen fluoride: Sb 2O 3 + 6 HF → 2 SbF 3 + 3 H 2O Because it is a polymer, SbF 3 is far less volatile than related compounds AsF 3 and SbCl 3. Three Sb–F bonds are short (192 pm) and three are long (261 pm). In solid SbF 3, the Sb centres have octahedral molecular geometry and are linked by bridging fluoride ligands. As well as some industrial applications, it is used as a reagent in inorganic and organofluorine chemistry. Sometimes called Swarts' reagent, is one of two principal fluorides of antimony, the other being SbF 5. Antimony trifluoride is the inorganic compound with the formula SbF 3.
