Al2O3 is Corundum structured and crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Al3+ is bonded to six equivalent O2- atoms to form a mixture of corner, edge, and face-sharing AlO6 octahedra. The corner-sharing octahedra tilt angles range from 48–60°. There is three shorter (1.87 Å) and three longer (1.99 Å) Al–O bond …
