Aluminum chloride is special in a way that the central atom, Al only has 3 bonds without having octet. In such case, ammonia can act as lewis base and donate its lone pair to form a coordinate covalent bond with aluminum forming Al3-NH3.

AlCl3 is a strong Lewis acid and reacts strongly with NH3, a base.
When react in molar ration 1:1, neutralization happened forming a salt.
