Iridium(III) iodide is an iodide of iridium, with the chemical formula of IrI₃.

Preparation

Iridium(III) iodide can be obtained by reducing iridium(IV) iodide with hydrogen at 210 °C. It can also be formed by the reaction of iridium dioxide or iridium(III) hydroxide with hydrogen iodide.

Chemical properties

Iridium(III) iodide is a dark brown solid that is insoluble in water. It is monoclinic like chromium trichloride. Its trihydrate is yellow and can be dehydrated into the dihydrate or anhydrous form on heating. Iridium(III) iodide also has a monohydrate.
