BiAgSeS is alpha Po-derived structured and crystallizes in the tetragonal P4/mmm space group. Ag(1) is bonded to four equivalent Se(1) and two equivalent S(1) atoms to form AgSe4S2 octahedra that share corners with six equivalent Ag(1)Se4S2 octahedra, edges with four equivalent Ag(1)Se4S2 octahedra, and edges with eight equivalent Bi(1)Se2S4 octahedra. The corner-sharing octahedra are not tilted. Bi(1) is bonded to two equivalent Se(1) and four equivalent S(1) atoms to form BiSe2S4 octahedra that share corners with six equivalent Bi(1)Se2S4 octahedra, edges with four equivalent Bi(1)Se2S4 octahedra, and edges with eight equivalent Ag(1)Se4S2 octahedra. The corner-sharing octahedra are not tilted. Se(1) is bonded to four equivalent Ag(1) and two equivalent Bi(1) atoms to form SeAg4Bi2 octahedra that share corners with six equivalent Se(1)Ag4Bi2 octahedra, edges with four equivalent Se(1)Ag4Bi2 octahedra, and edges with eight equivalent S(1)Ag2Bi4 octahedra. The corner-sharing octahedra are not tilted. S(1) is bonded to two equivalent Ag(1) and four equivalent Bi(1) atoms to form SAg2Bi4 octahedra that share corners with six equivalent S(1)Ag2Bi4 octahedra, edges with four equivalent S(1)Ag2Bi4 octahedra, and edges with eight equivalent Se(1)Ag4Bi2 octahedra. The corner-sharing octahedra are not tilted.
