Title: Materials Data on Al2O3 by Materials Project

Abstract

Al2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. The structure is three-dimensional. there are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to six equivalent O2- atoms to form a mixture of edge and corner-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 51°. All Al–O bond lengths are 1.93 Å. In the second Al3+ site, Al3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing AlO6 octahedra. The corner-sharing octahedra tilt angles range from 51–55°. There are a spread of Al–O bond distances ranging from 1.87–2.00 Å. O2- is bonded to four Al3+ atoms to form a mixture of distorted edge and corner-sharing OAl4 trigonal pyramids.
