FeSc2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Sc(1) is bonded to six equivalent S(1) atoms to form ScS6 octahedra that share corners with six equivalent Fe(1)S4 tetrahedra and edges with six equivalent Sc(1)S6 octahedra. Fe(1) is bonded to four equivalent S(1) atoms to form FeS4 tetrahedra that share corners with twelve equivalent Sc(1)S6 octahedra. The corner-sharing octahedral tilt angles are 56°. S(1) is bonded in a rectangular see-saw-like geometry to three equivalent Sc(1) and one Fe(1) atom.
