Materials Data on Zn(CrS2)4 by Materials Project
Zn(CrS2)4 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Cr+3.50+ sites. In the first Cr+3.50+ site, Cr+3.50+ is bonded to six S2- atoms to form CrS6 octahedra that share edges with two equivalent ZnS6 octahedra and edges with six CrS6 octahedra. There are two shorter (2.36 Å) and four longer (2.37 Å) Cr–S bond lengths. In the second Cr+3.50+ site, Cr+3.50+ is bonded to six equivalent S2- atoms to form CrS6 octahedra that share corners with six equivalent ZnS6 octahedra and edges with six equivalent CrS6 octahedra. The corner-sharing octahedral tilt angles are 7°. All Cr–S bond lengths are 2.41 Å. Zn2+ is bonded to six equivalent S2- atoms to form ZnS6 octahedra that share corners with six equivalent CrS6 octahedra and edges with six equivalent CrS6 octahedra. The corner-sharing octahedral tilt angles are 7°. All Zn–S bond lengths are 2.56 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a rectangular see-saw-like geometry to three Cr+3.50+ and one Zn2+ atom. In the second S2- site, S2- is bonded in a distorted T-shaped geometry to three equivalent Cr+3.50+ atoms.
