What is the name for the compound AlI_3?

May 15, 2016

$\text{Aluminum triiodide}$

Explanation:

Alternatively, even $\text{aluminum iodide}$ would be understood (there are reduced aluminum iodides, but they are rare beasts).

In the solid state, aluminum triiodide forms an iodo-bridged dimer, ${I}_{2} A l {\left({\mu}_{2} - I\right)}_{2} A l {I}_{2}$, i.e. $A {l}_{2} {I}_{6}$.
