Iodine oxide

Iodine oxides are chemical compounds and oxides of iodine. There exist multiple oxides as iodine has more than one oxidation state.

Iodine oxides [1].

Additional recommended knowledge

The iodide oxide free radical (IO) is a known Ozone depletion agent [2]. Atmospheric iodine containing compounds form iodine radicals which react with ozone to iodine oxide radicals (IO) and oxygen. The IO radicals then in turn participate in other ozone consuming chemical reactions.
