Diiodine oxide

Diiodine oxide, also known as iodohypoiodite, is an oxide of iodine that is equivalent to an acid anhydride of hypoiodous acid. This substance is unstable and it is very difficult to isolate.[2]

This article is about the compound I2O. For the molecule IO, see Iodine monoxide.

Preparation

Diiodine oxide can be prepared by reacting iodine with potassium iodate (KIO3) in 96% sulfuric acid and then extracting it into chlorinated solvents.[2]

Reactions

Diiodine oxide reacts with water to form hypoiodous acid:

I2O + H2O → 2 HIO
