Iodine monoxide is a binary inorganic compound of iodine and oxygen with the chemical formula IO•. A free radical, this compound is the simplest of many iodine oxides.[1][2][3] It is similar to the oxygen monofluoride, chlorine monoxide and bromine monoxide radicals.
Iodine monoxide can be obtained by the reaction between iodine and oxygen:[4]
Iodine monoxide decomposes to its prime elements:[citation needed]
Iodine monoxide reacts with nitric oxide:[5]
Atmospheric iodine atoms (e.g. from iodomethane) can react with ozone to produce the iodine monoxide radical:[6][5]
This process can contribute to ozone depletion.[citation needed]
