Materials Data on CrAuS2 by Materials Project
AuCrS2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Cr3+ is bonded to six equivalent S2- atoms to form edge-sharing CrS6 octahedra. All Cr–S bond lengths are 2.40 Å. Au1+ is bonded in a linear geometry to two equivalent S2- atoms. Both Au–S bond lengths are 2.32 Å. S2- is bonded in a 4-coordinate geometry to three equivalent Cr3+ and one Au1+ atom.
