The crystal structure described by YbTmS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Yb(1) is bonded to six equivalent S(1) atoms to form YbS6 octahedra that share corners with six equivalent Tm(1)S6 octahedra, edges with six equivalent Yb(1)S6 octahedra, and edges with six equivalent Tm(1)S6 octahedra. The corner-sharing octahedral tilt angles are 1°. Tm(1) is bonded to six equivalent S(1) atoms to form TmS6 octahedra that share corners with six equivalent Yb(1)S6 octahedra, edges with six equivalent Yb(1)S6 octahedra, and edges with six equivalent Tm(1)S6 octahedra. The corner-sharing octahedral tilt angles are 1°. S(1) is bonded to three equivalent Yb(1) and three equivalent Tm(1) atoms to form a mixture of corner and edge-sharing SYb3Tm3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
