It's a metal salt, so ionic.

- Wow, this answer is so simplified that it is totally incorrect. Sure, at the level of GCSE a metal + non-metal is ionic. However, due to the small difference between electronegativities of Aluminium and Chlorine (1.55) and the large charge density to size ratio of Aluminium, the chlorines are unable to completey remove the electrons from the Aluminium. Instead the electrons are shared, hence 3 single covalent bonds are formed. How else can you explain the fact that Aluminium Chloride sublimes at 180°C. ?? Not typical of an ionic compound !! Both Iodine and Carbon Dioxide sublime - both covalent.

Aluminium Chloride is COVALENT
