Well, you form an aluminate complex......

Explanation:

Much of the chemistry of aluminum and boron relates to the filling of the valence shell of the atom...... #AlCl_3# contains 6 valence electrons; it readily forms so-called #"ate complexes"# with donors to form aluminate salts.....e.g.

#AlCl_3(s) + LiCl(s) rarr Li^(+)AlCl_4^(-)#

...or....

#LiH(s) + AlH_3(s) rarr Li^(+)AlH_4^-#

Lithium aluminium hydride is the premier reducing agent in organic chemistry, and can deliver up to 4 hydrides per formula unit....
