Tetraiodine nonoxide is aniodine oxide with the chemical formula I4O9.
Tetraiodine nonoxide can be produced by reactingozone andiodine incarbon tetrachloride at −78 °C:[2][3]
It can also be produced by heatingiodic acid andphosphoric acid together:[4]
Tetraiodine nonoxide is a light yellow solid that can easilyhydrolyze. It decomposes above 75 °C:[2]
Likediiodine tetroxide, tetraiodine nonoxide contains both I(III) and I(V), anddisproportionate toiodate andiodide under alkaline conditions:[2]
It reacts with water to form iodic acid and iodine:[3]
