Periodyl fluoride
# Periodyl fluoride

Periodyl fluoride is an inorganic compound of iodine, fluorine, and oxygen with the chemical formula $IO_3F.$ The compound has been initially synthesized around 1950.

## Synthesis

Synthesis of periodyl fluoride is by fluorination of $KIO_4$ in liquid HF:

       $KIO_4$ + 2HF → $IO_3F$ + KF + $H_2O$

## Physical properties

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