Ammonium triiodide
Ammonium triiodide is the salt of the ammonium cation with the triiodide anion.
It is a very unstable compound and very easily ignited just by touch.
Sometimes the name ammonium triiodide is mistakenly used to refer to a different compound, nitrogen triiodide, or more precisely, the slightly more stable ammine, NI3 · NH3.
