title: Materials Data on Cr5S8 by Materials Project

description: Cr5S8 is beta indium sulfide-like structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are eight inequivalent Cr+3.20+ sites. In the first Cr+3.20+ site, Cr+3.20+ is bonded to six S2- atoms to form a mixture of corner 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 2.39–2.41 Å. In the second Cr+3.20+ site, Cr+3.20+ is bonded to six S2- atoms to form a mixture of corner and face-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 48–53°. There are three shorter (2.38 Å) and three longer (2.42 Å) Cr–S bond lengths. In the third Cr+3.20+ site, Cr+3.20+ is bonded to six S2- atoms to form a mixture of edge, corner, and face-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are a spread of Cr–S bond distances ranging from 2.29–2.48 Å. In the fourth Cr+3.20+ site, Cr+3.20+ is bonded to six S2- atoms to form a mixture of edge, corner, and face-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are a spread of Cr–S bond distances ranging from 2.30–2.46 Å. In the fifth Cr+3.20+ site, Cr+3.20+ is bonded to six S2- atoms to form a mixture of edge, corner, and face-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are a spread of Cr–S bond distances ranging from 2.30–2.47 Å. In the sixth Cr+3.20+ site, Cr+3.20+ is bonded to six S2- atoms to form a mixture of edge, corner, and face-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Cr–S bond distances ranging from 2.32–2.40 Å. In the seventh Cr+3.20+ site, Cr+3.20+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 48–50°. There are a spread of Cr–S bond distances ranging from 2.31–2.42 Å. In the eighth Cr+3.20+ site, Cr+3.20+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 50–51°. There are a spread of Cr–S bond distances ranging from 2.30–2.44 Å. There are twelve inequivalent S2- sites. In the first S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr+3.20+ atoms. In the second S2- site, S2- is bonded to four Cr+3.20+ atoms to form a mixture of distorted edge and corner-sharing SCr4 trigonal pyramids. In the third S2- site, S2- is bonded to four Cr+3.20+ atoms to form a mixture of distorted edge and corner-sharing SCr4 trigonal pyramids. In the fourth S2- site, S2- is bonded in a 3-coordinate geometry to three Cr+3.20+ atoms. In the fifth S2- site, S2- is bonded in a distorted T-shaped geometry to three Cr+3.20+ atoms. In the sixth S2- site, S2- is bonded to four Cr+3.20+ atoms to form a mixture of edge and corner-sharing SCr4 trigonal pyramids. In the seventh S2- site, S2- is bonded to four Cr+3.20+ atoms to form a mixture of distorted edge and corner-sharing SCr4 trigonal pyramids. In the eighth S2- site, S2- is bonded in a distorted T-shaped geometry to three Cr+3.20+ atoms. In the ninth S2- site, S2- is bonded in a distorted T-shaped geometry to three Cr+3.20+ atoms. In the tenth S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr+3.20+ atoms. In the eleventh S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr+3.20+ atoms. In the twelfth S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr+3.20+ atoms.
