Title: Materials Data on Fe3O4 by Materials Project

Abstract

Fe3O4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Fe+2.67+ sites. In the first Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 7–56°. There are a spread of Fe–O bond distances ranging from 2.01–2.10 Å. In the second Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 7–55°. There are a spread of Fe–O bond distances ranging from 1.94–2.13 Å. In the third Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 6–56°. There are a spread of Fe–O bond distances ranging from 1.97–2.11 Å. In the fourth Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing FeO6 octahedra.
