Materials Data on Cr3S4 by Materials Project

Cr3S4 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are six inequivalent Cr+2.67+ sites. In the first Cr+2.67+ site, Cr+2.67+ is bonded to six S2- atoms to form a mixture of corner, edge, and face-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 48–53°. There are a spread of Cr–S bond distances ranging from 2.40–2.46 Å. In the second Cr+2.67+ site, Cr+2.67+ is bonded to six S2- atoms to form a mixture of corner, edge, and face-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 48–52°. There are a spread of Cr–S bond distances ranging from 2.40–2.48 Å. In the third Cr+2.67+ site, Cr+2.67+ is bonded to six S2- atoms to form a mixture of corner, edge, and face-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 49–53°. There are a spread of Cr–S bond distances ranging from 2.34–2.50 Å. In the fourth Cr+2.67+ site, Cr+2.67+ is bonded to six S2- atoms to form a mixture of corner, edge, and face-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 48–51°. There are a spread of Cr–S bond distances ranging from 2.35–2.44 Å. In the fifth Cr+2.67+ site, Cr+2.67+ is bonded to six S2- atoms to form a mixture of corner, edge, and face-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 49–52°. There are a spread of Cr–S bond distances ranging from 2.34–2.49 Å. In the sixth Cr+2.67+ site, Cr+2.67+ is bonded to six S2- atoms to form a mixture of corner, edge, and face-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 48–51°. There are a spread of Cr–S bond distances ranging from 2.35–2.43 Å. There are eight inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to four Cr+2.67+ atoms. In the second S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr+2.67+ atoms. In the third S2- site, S2- is bonded in a 5-coordinate geometry to five Cr+2.67+ atoms. In the fourth S2- site, S2- is bonded to five Cr+2.67+ atoms to form a mixture of distorted corner and edge-sharing SCr5 trigonal bipyramids. In the fifth S2- site, S2- is bonded to five Cr+2.67+ atoms to form a mixture of distorted corner and edge-sharing SCr5 trigonal bipyramids. In the sixth S2- site, S2- is bonded to five Cr+2.67+ atoms to form distorted edge-sharing SCr5 trigonal bipyramids. In the seventh S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to four Cr+2.67+ atoms. In the eighth S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr+2.67+ atoms.
