Materials Data on Cu(RhS2)2 by Materials Project
CuRh2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Rh+3.50+ is bonded to six equivalent S2- atoms to form RhS6 octahedra that share corners with six equivalent CuS4 tetrahedra and edges with six equivalent RhS6 octahedra. All Rh–S bond lengths are 2.38 Å. Cu1+ is bonded to four equivalent S2- atoms to form CuS4 tetrahedra that share corners with twelve equivalent RhS6 octahedra. The corner-sharing octahedral tilt angles are 58°. All Cu–S bond lengths are 2.30 Å. S2- is bonded to three equivalent Rh+3.50+ and one Cu1+ atom to form a mixture of distorted edge and corner-sharing SCuRh3 trigonal pyramids.
