Aluminium(I) iodide

The name "aluminium iodide" is commonly assumed to define the triiodide or that is dimer. In fact, a monoiodide also enjoys a role in the Al-I system, although composition AlI is unstable at room temperature with respect to the triiodide<3>

6 AlI → Al2I6 + 4 Al

An illustrative derivative of aluminium monoiodide is the cyclic adduct developed with triethylamine, AI4I4(NEt3)4.

Safety
