LiDyS2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. Li(1) is bonded to six S(1,1) atoms to form LiS6 octahedra that share corners with two equivalent Dy(1)S6 octahedra, corners with four 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 octahedral tilt angles range from 0-3°. Dy(1) is bonded to six S(1,1) atoms to form DyS6 octahedra that share corners with two equivalent Li(1)S6 octahedra, corners with four 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 octahedral tilt angles range from 0-3°. There are three inequivalent S sites. In the first S site, S(1) is bonded to three equivalent Li(1) and three equivalent Dy(1) atoms to form a mixture of corner and edge-sharing SLi3Dy3 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. In the second S site, S(1) is bonded to three equivalent Li(1) and three equivalent Dy(1) atoms to form a mixture of corner and edge-sharing SLi3Dy3 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. In the third S site, S(1) is bonded to three equivalent Li(1) and three equivalent Dy(1) atoms to form a mixture of corner and edge-sharing SLi3Dy3 octahedra. The corner-sharing octahedral tilt angles range from 0-3°.
