The compound described by CdYb2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Yb(1) is bonded to six equivalent S(1) atoms to form YbS6 octahedra that share corners with six equivalent Cd(1)S4 tetrahedra and edges with six equivalent Yb(1)S6 octahedra. Cd(1) is bonded to four equivalent S(1) atoms to form CdS4 tetrahedra that share corners with twelve equivalent Yb(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 Yb(1) and one Cd(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
