Question

What is the name for the compound `AlI_3`?

Answer 1

`"Aluminum triiodide"`

Explanation:

Alternatively, even `"aluminum iodide"` would be understood (there are reduced aluminum iodides, but they are rare beasts).

In the solid state, aluminum triiodide forms an iodo-bridged dimer, `I_2Al(mu_2-I)_2AlI_2`, i.e. `Al_2I_6`.
