Materials Data on Al2O3 by Materials Project
Abstract
Al2O3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 57°. There are a spread of Al–O bond distances ranging from 1.86–2.01 Å. In the second Al3+ site, Al3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Al–O bond distances ranging from 1.87–2.14 Å. In the third Al3+ site, Al3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Al–O bond distances ranging from 1.87–2.13 Å. In the fourth Al3+ site, Al3+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing AlO6 octahedra. The corner-sharing octahedral tilt angles are 57°. There are a spread of Al–O bond distances ranging from 1.86–2.01 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted square co-planar geometry to four Al3+ atoms. In the second O2- site, O2- is bonded to four Al3+ atoms to form corner-sharing OAl4 tetrahedra.
