Iridium tetroxide (IrO4, Iridium(VIII) oxide) is a binary compound of oxygen and iridium in oxidation state +VIII. [1] [2] This compound was formed by photochemical rearrangement of [(η1O2)IrO2] in solid argon at a temperature of 6 K (−267 °C, −449 °F). At higher temperatures the oxide is unstable.[3] The detection of the iridium tetroxide cation by infrared photodissociation spectroscopy with formal oxidation state IX has been reported. [4] [5]
