Synthesis

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

I2O5 + 3 IF5 → 5 IOF3

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

I2 + O2 + 3 F2 → 2 IOF3

Or alternately by reaction of iodine pentafluoride with water:

IF5 + H2O → IOF3 + 2 HF

Physical properties

Iodosyl trifluoride forms hygroscopic colorless needles. Reacts with water. [4] [ how? ]

Chemical properties

Iodosyl trifluoride is hygroscopic and decomposes into IO2F and IF5 at 110 °C (230 °F). [5]
