CdTm2S4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Tm(1) is bonded to six equivalent S(1) atoms to form TmS6 octahedra that share corners with six equivalent Cd(1)S4 tetrahedra and edges with six equivalent Tm(1)S6 octahedra. Cd(1) is bonded to four equivalent S(1) atoms to form CdS4 tetrahedra that share corners with twelve equivalent Tm(1)S6 octahedra. The corner-sharing octahedral tilt angles are 57°. S(1) is bonded to three equivalent Tm(1) and one Cd(1) atom to form a mixture of distorted corner and edge-sharing STm3Cd trigonal pyramids.
