Aluminium chloride (AlCl<sub>3</sub>) is a compound of aluminium and chlorine. The solid has a low melting and boiling point, and is covalently bonded. It sublimes at 178 °C. Molten AlCl<sub>3</sub> conducts electricity poorly,[1] unlike more ionic halides such as sodium chloride. It exists in the solid state as a six-coordinate layer lattice.
