Iridium compounds are compounds containing the element iridium (Ir). Iridium forms compounds in oxidation states between −3 and +9, but the most common oxidation states are +1, +2, +3, and +4.[2] Well-characterized compounds containing iridium in the +6 oxidation state include IrF6 and the oxides Sr2MgIrO6 and Sr2CaIrO6.[2][3] iridium(VIII) oxide (IrO4) was generated under matrix isolation conditions at 6 K in argon.[4] The highest oxidation state (+9), which is also the highest recorded for any element, is found in gaseous [IrO4]+.[1]
