Ammonium Iridi-nitrite, (NH4)3Ir(NO2)6






Ammonium Iridi-nitrite, (NH4)3Ir(NO2)6, may be prepared by addition of sodium nitrite and ammonium sulphate to a warm solution of iridium sulphate. It separates out as a white powder, similar to the potassium salt. When boiled with water it evolves nitrogen, and heated in the dry state it detonates.
