Materials Data on Cr(InS2)2 by Materials Project

Cr(InS2)2 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Cr2+ is bonded to four equivalent S2- atoms to form CrS4 tetrahedra that share corners with twelve equivalent InS6 octahedra. The corner-sharing octahedral tilt angles are 56°. All Cr–S bond lengths are 2.39 Å. In3+ is bonded to six equivalent S2- atoms to form InS6 octahedra that share corners with six equivalent CrS4 tetrahedra and edges with six equivalent InS6 octahedra. All In–S bond lengths are 2.66 Å. S2- is bonded in a distorted rectangular see-saw-like geometry to one Cr2+ and three equivalent In3+ atoms.
