Iridium(IV) iodide is a binary chemical compound of
iridium and
iodide with the chemical formula IrI
4.
[1]
[2]
[3]
Iridium(IV) iodide can be obtained by reacting dipotassium hexachloroiridate or hexachloroiridic acid with an aqueous solution of potassium iodide. [4] [5]
Iridium tetraiodide forms black crystals, does not dissolve in water and alcohol. [6] [7] [8] In alkali metal iodide solutions, the compound dissolves easily to give a ruby red solution, forming complex salts. [5]
The compound decomposes when heated:[ citation needed]
Iridium(IV) iodide can be used as a catalyst in organic chemistry. [9] [8]
