Title: Materials Data on Fe7S8 by Materials Project

Abstract

Fe7S8 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are four inequivalent Fe+2.29+ sites. In the first Fe+2.29+ site, Fe+2.29+ is bonded in a 5-coordinate geometry to five S2- atoms. There are a spread of Fe–S bond distances ranging from 2.10–2.29 Å. In the second Fe+2.29+ site, Fe+2.29+ is bonded to six S2- atoms to form a mixture of face, edge, and corner-sharing FeS6 octahedra. The corner-sharing octahedra tilt angles range from 44–59°. There are a spread of Fe–S bond distances ranging from 2.18–2.38 Å. In the third Fe+2.29+ site, Fe+2.29+ is bonded to six S2- atoms to form a mixture of face, edge, and corner-sharing FeS6 octahedra. The corner-sharing octahedra tilt angles range from 44–59°. There are a spread of Fe–S bond distances ranging from 2.19–2.46 Å. In the fourth Fe+2.29+ site, Fe+2.29+ is bonded to six S2- atoms to form a mixture of distorted face, edge, and corner-sharing FeS6 octahedra. The corner-sharing octahedra tilt angles range from 52–53°. There are a spread of Fe–S bond distances ranging from 2.16–2.39 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to five Fe+2.29+ atoms. In themore » second S2- site, S2- is bonded in a 5-coordinate geometry to five Fe+2.29+ atoms.
