AgBiS2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Ag(1) is bonded to two equivalent S(2) and four equivalent S(1) 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 Bi(1)S6 octahedra. The corner-sharing octahedra are not tilted. Bi(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form BiS6 octahedra that share corners with six equivalent Bi(1)S6 octahedra, edges with four equivalent Bi(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 four equivalent Ag(1) and two equivalent Bi(1) atoms to form SAg4Bi2 octahedra that share corners with six equivalent S(1)Ag4Bi2 octahedra, edges with four equivalent S(1)Ag4Bi2 octahedra, and edges with eight equivalent S(2)Ag2Bi4 octahedra. The corner-sharing octahedra are not tilted. In the second S site, S(2) is bonded to two equivalent Ag(1) and four equivalent Bi(1) atoms to form SAg2Bi4 octahedra that share corners with six equivalent S(2)Ag2Bi4 octahedra, edges with four equivalent S(2)Ag2Bi4 octahedra, and edges with eight equivalent S(1)Ag4Bi2 octahedra. The corner-sharing octahedra are not tilted.
