Iodosyl trifluoride
# Iodosyl trifluoride

Iodosyl trifluoride is an inorganic compound of iodine, fluorine, and oxygen with the chemical formula $IOF_3.$

## Synthesis

Synthesis of iodosyl trifluoride can be done by a reaction of iodine pentoxide with iodine pentafluoride.

       $I_2O_5$ + $3IF_5$ → $5IOF_3$

Synthesis can be by a reaction of gases:

       $I_2$ + $O_2$ + $3F_2$ → $2IOF_3$

Or alternately by reaction of iodine pentafluoride with water:

       $IF_5$ + $H_2O$ → $IOF_3$ + 2HF

## Physical properties

Iodosyl trifluoride forms hygroscopic colorless needles. Reacts with water.

## Chemical properties

Iodosyl trifluoride is hygroscopic and decomposes into $IO_2F$ and $IF_5$ at 110 °C.
