dot cross diagram

the ionic lattice has a structure in which six chloride ions surround one aluminium ion, in an octahedral arrangement. Draw a 3D diagram to show this arrangement.

Did you look up "octahedral" in Mr. Google (your friend)?
Octahedral derives from an octahedron so the chloride ions are arranged in an octahedron (if you don't know what it is search it up - it's a platonic solid) at its points. The aluminium ion is in the middle of that.
