Iridium(VI) fluoride is a volatile and highly reactive yellow solid, with an octahedral molecular structure (Ir–F bond length is 183.3 pm). It is the only compound with iridium in its highest oxidation state, 6+. It is formed directly at 300 °C from the constituent elements, iridium and fluorine, but it is thermally unstable and must be frozen out of the gaseous reaction mixture to avoid dissociation.
