Periodyl fluoride

Periodyl fluoride is an inorganic compound of iodine, fluorine, and oxygen with the chemical formula IO3F. The compound has been initially synthesized around 1950.

Synthesis
Synthesis of periodyl fluoride is by fluorination of KIO4 in liquid HF:


 * KIO4 + 2HF -> IO3F + KF + H2O

Physical properties
Periodyl fluoride forms colorless crystals. Decomposes at 90 to 100 °C.
