  aluminium chloride
The structure of aluminium chloride is often represented as Al Cl
It consists of hexagonal close-packed layers of chloride ions in which two-thirds of the octahedral holes between every other pair of Cl planes are occupied by aluminium ions.
Aluminium bromide and iodide do not share these properties, existing as dimers in the solid phase and not showing such dramatic changes on melting.
