Cr2S3 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are four inequivalent Cr3+ sites. In the first Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of edge, face, and corner-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are three shorter (2.37 Å) and three longer (2.42 Å) Cr–S bond lengths. In the second Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of face and corner-sharing CrS6 octahedra. The corner-sharing octahedra tilt angles range from 46–51°. There are three shorter (2.36 Å) and three longer (2.44 Å) Cr–S bond lengths. In the third Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 46°. There are three shorter (2.38 Å) and three longer (2.39 Å) Cr–S bond lengths. In the fourth Cr3+ site, Cr3+ is bonded to six S2- atoms to form a mixture of edge, face, and corner-sharing CrS6 octahedra. The corner-sharing octahedral tilt angles are 48°. There are three shorter (2.39 Å) and three longer (2.40 Å) Cr–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr3+ atoms. In the second S2- site, S2- is bonded in a rectangular see-saw-like geometry to four Cr3+ atoms.
