Autoignition =Antimony trifluoride, SbF3, sometimes called Swart's reagent is a
fluoride ofantimony . It appears as a lightgrey crystalline material often used in dyeing and pottery.SbF3 can be prepared by reactingantimony trioxide , Sb2O3, with HF [ Greenwood&Earnshaw] or by direct reaction of the elements.Cotton&Wilkinson6th] In the solid state molecules of SbF3 are linked by fluorine bridges so that each Sb atom has a coordination number of 6.The substance is highly
corrosive and can burn skin and cause eye damage. It can also damage other organs such as theheart ,liver andkidneys and causeulcers . [1998-2004 New Jersey Department of Health and Senior Services.

fluorination reagent by the belgium chemistFrédéric Jean Edmond Swarts in 1892.References
