Iodosyl trifluoride

Iodosyl trifluoride is an inorganic compound of iodine, fluorine, and oxygen with the chemical formula IOF3.

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


 * I2O5 + 3IF5 -> 5IOF3

Synthesis can be by a reaction of gases:
 * I2 + O2 + 3F2 -> 2IOF3

Or alternately by reaction of iodine pentafluoride with water:


 * IF5 + H2O → IOF3 + 2HF

Physical properties
Iodosyl trifluoride forms hygroscopic colorless needles. Reacts with water.

Chemical properties
Iodosyl trifluoride is hygroscopic and decomposes into IO2F and IF5 at 110 °C.
