AgSnS2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Ag(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form AgS6 octahedra that share corners with six equivalent Ag(1)S6 octahedra, edges with four equivalent Ag(1)S6 octahedra, and edges with eight equivalent Sn(1)S6 octahedra. The corner-sharing octahedra are not tilted. Sn(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form SnS6 octahedra that share corners with six equivalent Sn(1)S6 octahedra, edges with four equivalent Sn(1)S6 octahedra, and edges with eight equivalent Ag(1)S6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Ag(1) and four equivalent Sn(1) atoms to form SAg2Sn4 octahedra that share corners with six equivalent S(1)Ag2Sn4 octahedra, edges with four equivalent S(1)Ag2Sn4 octahedra, and edges with eight equivalent S(2)Ag4Sn2 octahedra. The corner-sharing octahedra are not tilted. In the second S site, S(2) is bonded to four equivalent Ag(1) and two equivalent Sn(1) atoms to form SAg4Sn2 octahedra that share corners with six equivalent S(2)Ag4Sn2 octahedra, edges with four equivalent S(2)Ag4Sn2 octahedra, and edges with eight equivalent S(1)Ag2Sn4 octahedra. The corner-sharing octahedra are not tilted.
