Iodine oxide

Iodine oxides are chemical compounds of oxygen and iodine. Iodine has at least three stable oxides which are isolable in bulk, diiodine tetroxide, iodine pentoxide, and diiodine hexaoxide, but a number of other oxides are formed in trace quantities or have been hypothesized to exist. The most significant of these is iodine pentoxide, which is distinguished by being the most thermodynamically and kinetically stable of all halogen oxides. The chemistry of these compounds is complicated, with only a few having been well characterized. Many have been detected in the atmosphere and are believed to be particularly important in the marine boundary layer.
