The Materials Project

Al2O3 is Corundum-like structured and crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Al3+ is bonded to six O2- atoms to form a mixture of face, edge, and corner-sharing AlO6 octahedra. The corner-sharing octahedra tilt angles range from 51–71°. There are a spread of Al–O bond distances ranging from 1.87–2.03 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Al3+ atoms to form a mixture of distorted edge and corner-sharing OAl4 tetrahedra. In the second O2- site, O2- is bonded to four equivalent Al3+ atoms to form a mixture of distorted edge and corner-sharing OAl4 trigonal pyramids.
