Iridium(IV) iodide is a binary chemical compound of iridium and iodide with the chemical formula IrI4.[1][2][3]
Preparation
Iridium(IV) iodide can be obtained by reacting dipotassium hexachloroiridate or hexachloroiridic acid with an aqueous solution of potassium iodide.[4][5]
Properties
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]
- IrI
4 → Ir + 2I
2
- IrI
Uses
Iridium(IV) iodide can be used as a catalyst in organic chemistry.[9][8]
