AlCl3 is basically an ionic compound, but according to Fajan's rules, every ionic compound has some covalent character in it. From the rules, phi=charge on cation/charge on anion where phi is the ionic potential of the cation.Now Al3+ has high +ve charge on it, so it can distort the cl-cation easily, thus inducing covalent character into it.See Wikipedia for more details.rom the rules, phi=charge on cation/charge on anion where phi is the ionic potential of the cation.

Anhydrous aluminium chloride is a powerful Lewis acid, capable of forming Lewis acid-base adducts with even weak Lewis bases such as benzophenone and mesitylene. It forms tetrachloroaluminate AlCl 4 â in the presence of chloride ions.n the melt, aluminium trichloride exists as the dimer Al 2 Cl 6, with tetracoordinate aluminium. This change in structure is related to the lower density of the liquid phase (1.78 g/cm 3) vs solid aluminium trichloride (2.48 g/cm 3).
