CdY2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Y(1) is bonded to six equivalent S(1) atoms to form YS6 octahedra that share corners with six equivalent Cd(1)S4 tetrahedra and edges with six equivalent Y(1)S6 octahedra. Cd(1) is bonded to four equivalent S(1) atoms to form CdS4 tetrahedra that share corners with twelve equivalent Y(1)S6 octahedra. The corner-sharing octahedral tilt angles are 57°. S(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Y(1) and one Cd(1) atom.
