Materials Data on Fe2O3 by Materials Project

Fe2O3 is Corundum-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form a mixture of face, edge, and corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 50–73°. There are a spread of Fe–O bond distances ranging from 1.99–2.13 Å. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form a mixture of distorted face, edge, and corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 51–72°. There are a spread of Fe–O bond distances ranging from 1.99–2.17 Å. In the third Fe3+ site, Fe3+ is bonded to six O2- atoms to form a mixture of distorted face, edge, and corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 51–72°. There are a spread of Fe–O bond distances ranging from 1.98–2.20 Å. In the fourth Fe3+ site, Fe3+ is bonded to six O2- atoms to form a mixture of distorted face, edge, and corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 50–72°. There are a spread of Fe–O bond distances ranging from 1.97–2.17 Å. In the fifth Fe3+ site, Fe3+ is bonded to six O2- atoms to form a mixture of face, edge, and corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 49–72°. There are a spread of Fe–O bond distances ranging from 1.99–2.13 Å. In the sixth Fe3+ site, Fe3+ is bonded to six O2- atoms to form a mixture of distorted face, edge, and corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 51–73°.
