MgYb2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Mg(1) is bonded to four equivalent S(1) atoms to form MgS4 tetrahedra that share corners with twelve equivalent Yb(1)S6 octahedra. The corner-sharing octahedral tilt angles are 55°. Yb(1) is bonded to six equivalent S(1) atoms to form YbS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra and edges with six equivalent Yb(1)S6 octahedra. S(1) is bonded in a rectangular see-saw-like geometry to one Mg(1) and three equivalent Yb(1) atoms.
