FeLu2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Lu(1) is bonded to six equivalent S(1) atoms to form LuS6 octahedra that share corners with six equivalent Fe(1)S4 tetrahedra and edges with six equivalent Lu(1)S6 octahedra. Fe(1) is bonded to four equivalent S(1) atoms to form FeS4 tetrahedra that share corners with twelve equivalent Lu(1)S6 octahedra. The corner-sharing octahedral tilt angles are 55°. S(1) is bonded in a rectangular see-saw-like geometry to three equivalent Lu(1) and one Fe(1) atom.
