The material structure described by Cr4FeCoS8 is Spinel-derived structured and crystallizes in the cubic F-43m space group. Cr(1) is bonded to three equivalent S(1) and three equivalent S(2) atoms to form CrS6 octahedra that share corners with three equivalent Fe(1)S4 tetrahedra, corners with three equivalent Co(1)S4 tetrahedra, and edges with six equivalent Cr(1)S6 octahedra. Fe(1) is bonded to four equivalent S(2) atoms to form FeS4 tetrahedra that share corners with twelve equivalent Cr(1)S6 octahedra. The corner-sharing octahedral tilt angles are 57°. Co(1) is bonded to four equivalent S(1) atoms to form CoS4 tetrahedra that share corners with twelve equivalent Cr(1)S6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to three equivalent Cr(1) and one Co(1) atom. In the second S site, S(2) is bonded to three equivalent Cr(1) and one Fe(1) atom to form a mixture of distorted corner and edge-sharing SCr3Fe trigonal pyramids. is represented by the CIF file [CIF]
