Cr3In(CoS4)2 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 Co(1)S4 tetrahedra, edges with two equivalent In(1)S6 octahedra, and edges with four equivalent Cr(1)S6 octahedra. Co(1) is bonded to one S(1) and three equivalent S(2) atoms to form CoS4 tetrahedra that share corners with three equivalent In(1)S6 octahedra and corners with nine equivalent Cr(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 54-62°. In(1) is bonded to six equivalent S(2) atoms to form InS6 octahedra that share corners with six equivalent Co(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 Co(1) atom. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to two equivalent Cr(1), one Co(1), and one In(1) atom.
