The crystal structure described by TmAgS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Tm(1) is bonded to six equivalent S(1) atoms to form TmS6 octahedra that share corners with six equivalent Ag(1)S6 octahedra, edges with six equivalent Tm(1)S6 octahedra, and edges with six equivalent Ag(1)S6 octahedra. The corner-sharing octahedral tilt angles are 3°. Ag(1) is bonded to six equivalent S(1) atoms to form AgS6 octahedra that share corners with six equivalent Tm(1)S6 octahedra, edges with six equivalent Tm(1)S6 octahedra, and edges with six equivalent Ag(1)S6 octahedra. The corner-sharing octahedral tilt angles are 3°. S(1) is bonded to three equivalent Tm(1) and three equivalent Ag(1) atoms to form a mixture of edge and corner-sharing STm3Ag3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
