Iridium(III) iodide is an iodide of iridium, with the chemical formula of IrI3.
Iridium(III) iodide can be obtained by reducing iridium(IV) iodide with hydrogen at 210 °C.[2] It can also be formed by the reaction of iridium dioxide[3] or iridium(III) hydroxide with hydrogen iodide.[4]
Iridium(III) iodide is a dark brown solid that is insoluble in water.[1] It is monoclinic like chromium trichloride.[5][6] Its trihydrate is yellow and can be dehydrated into the dihydrate or anhydrous form on heating. Iridium(III) iodide also has a monohydrate.[3][7]
