FeCr2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Cr(1) is bonded to six equivalent S(1) atoms to form CrS6 octahedra that share corners with six equivalent Fe(1)S4 tetrahedra and edges with six equivalent Cr(1)S6 octahedra. Fe(1) is bonded to four equivalent S(1) atoms to form FeS4 tetrahedra that share corners with twelve equivalent Cr(1)S6 octahedra. The corner-sharing octahedral tilt angles are 58°. S(1) 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.
