YbAgS2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Yb(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form YbS6 octahedra that share corners with six equivalent Yb(1)S6 octahedra, edges with four equivalent Yb(1)S6 octahedra, and edges with eight equivalent Ag(1)S6 octahedra. The corner-sharing octahedra are not tilted. 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 Yb(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 Yb(1) and two equivalent Ag(1) atoms to form SYb4Ag2 octahedra that share corners with six equivalent S(1)Yb4Ag2 octahedra, edges with four equivalent S(1)Yb4Ag2 octahedra, and edges with eight equivalent S(2)Yb2Ag4 octahedra. The corner-sharing octahedra are not tilted. In the second S site, S(2) is bonded to two equivalent Yb(1) and four equivalent Ag(1) atoms to form SYb2Ag4 octahedra that share corners with six equivalent S(2)Yb2Ag4 octahedra, edges with four equivalent S(2)Yb2Ag4 octahedra, and edges with eight equivalent S(1)Yb4Ag2 octahedra. The corner-sharing octahedra are not tilted.
