YbAgS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Yb(1) is bonded to six equivalent S(1) atoms to form YbS6 octahedra that share corners with six equivalent Ag(1)S6 octahedra, edges with six equivalent Yb(1)S6 octahedra, and edges with six equivalent Ag(1)S6 octahedra. The corner-sharing octahedral tilt angles are 2°. Ag(1) is bonded to six equivalent S(1) atoms to form AgS6 octahedra that share corners with six equivalent Yb(1)S6 octahedra, edges with six equivalent Yb(1)S6 octahedra, and edges with six equivalent Ag(1)S6 octahedra. The corner-sharing octahedral tilt angles are 2°. S(1) is bonded to three equivalent Yb(1) and three equivalent Ag(1) atoms to form a mixture of edge and corner-sharing SYb3Ag3 octahedra. The corner-sharing octahedra are not tilted.
