Useful:

• Uses: Ammonium Hexachloroiridate(IV) is a reagent used for research applications and is used for catalytic production on hydrogen.It is a key intermediate in the isolation of iridium from ores. Most other metals form insoluble sulfides when aqueous solutions of their chlorides are treated with hydrogen sulfide, but [IrCl6]2? resists ligand substitution. Upon heating under hydrogen, the solid salt converts to the metal:(NH4)2[IrCl6] + 2 H2→ Ir + 6 HCl + 2 NH3 Iridium complexes are generated from ammonium hexachloroiridate.
