LiDyS2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Li(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form LiS6 octahedra that share corners with six equivalent Li(1)S6 octahedra, edges with four equivalent Li(1)S6 octahedra, and edges with eight equivalent Dy(1)S6 octahedra. The corner-sharing octahedra are not tilted. Dy(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form DyS6 octahedra that share corners with six equivalent Dy(1)S6 octahedra, edges with four equivalent Dy(1)S6 octahedra, and edges with eight equivalent Li(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 two equivalent Li(1) and four equivalent Dy(1) atoms to form SLi2Dy4 octahedra that share corners with six equivalent S(1)Li2Dy4 octahedra, edges with four equivalent S(1)Li2Dy4 octahedra, and edges with eight equivalent S(2)Li4Dy2 octahedra. The corner-sharing octahedra are not tilted. In the second S site, S(2) is bonded to four equivalent Li(1) and two equivalent Dy(1) atoms to form SLi4Dy2 octahedra that share corners with six equivalent S(2)Li4Dy2 octahedra, edges with four equivalent S(2)Li4Dy2 octahedra, and edges with eight equivalent S(1)Li2Dy4 octahedra. The corner-sharing octahedra are not tilted.
