YbAgS2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. Yb(1) is bonded to six S(1,1) atoms to form YbS6 octahedra that share corners with two equivalent Ag(1)S6 octahedra, corners with four 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 octahedral tilt angles range from 0-4°. Ag(1) is bonded to six S(1,1) atoms to form AgS6 octahedra that share corners with two equivalent Yb(1)S6 octahedra, corners with four 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 octahedral tilt angles range from 0-4°. There are two inequivalent S sites. In the first S site, 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 octahedral tilt angles range from 0-4°. In the second S site, 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 octahedral tilt angles range from 0-4°.
