$\underset{\left(\mathrm{Unstable}\right)}{2{\mathrm{FeI}}_3}⟶\underset{\left(\mathrm{Stable}\right)}{2{\mathrm{FeI}}_2}+{\mathrm{I}}_2$

Due to strong reducing nature of ${\mathrm{I}}^{-}$

$2{\mathrm{Fe}}^{3+}+2{\mathrm{I}}^{-}⟶2{\mathrm{Fe}}^{2+}+{\mathrm{I}}_2$ remaining halides of ${\mathrm{Fe}}^{2+}$ and ${\mathrm{Fe}}^{3+}$ are stable.
