The aluminum species accepts electron density from the chloride ion, and can be described as #sp^3# hybridized.

Explanation:

Before the reaction, the metal centre could be described as #sp^2# hybridized, and trigonal planar in structure. Much of the chemistry of aluminum can be described in terms of the metal filling its vacant #p# orbital to give a #sp^3# description.

What is the new geometry about #Al#??
