The compound described by Cr3Cu2SbS8 is Spinel-derived structured and crystallizes in the trigonal R-3m space group. Cr(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form CrS6 octahedra that share corners with six equivalent Cu(1)S4 tetrahedra, edges with two equivalent Sb(1)S6 octahedra, and edges with four equivalent Cr(1)S6 octahedra. Cu(1) is bonded to one S(1) and three equivalent S(2) atoms to form CuS4 tetrahedra that share corners with three equivalent Sb(1)S6 octahedra and corners with nine equivalent Cr(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 54-65°. Sb(1) is bonded to six equivalent S(2) atoms to form SbS6 octahedra that share corners with six equivalent Cu(1)S4 tetrahedra and edges with six equivalent Cr(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Cr(1) and one Cu(1) atom. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to two equivalent Cr(1), one Cu(1), and one Sb(1) atom. is represented by the CIF file [CIF]
