Iodosyl trifluoride is an inorganic compound of iodine, fluorine, and oxygen with the chemical formula IOF3.[1]

Synthesis

Synthesis of iodosyl trifluoride can be done by a reaction of iodine pentoxide with iodine pentafluoride.[2]

I2O5 + 3IF5 → 5IOF3

Synthesis can be by a reaction of gases:[3]

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.[4]

Chemical properties

Iodosyl trifluoride is hygroscopic and decomposes into IO2F and IF5 at 110 °C.[5]
