Sn(Li)S2 is Caswellsilverite-like structured and crystallizes in the trigonal P-3m1 space group. Li(1) is bonded to six equivalent S(1) atoms to form LiS6 octahedra that share corners with twelve equivalent Sn(1)S6 octahedra, edges with six equivalent Li(1)S6 octahedra, and faces with two equivalent Sn(1)S6 octahedra. The corner-sharing octahedral tilt angles are 47°. Sn(1) is bonded to six equivalent S(1) atoms to form SnS6 octahedra that share corners with twelve equivalent Li(1)S6 octahedra, edges with six equivalent Sn(1)S6 octahedra, and faces with two equivalent Li(1)S6 octahedra. The corner-sharing octahedral tilt angles are 47°. S(1) is bonded in a 6-coordinate geometry to three equivalent Li(1) and three equivalent Sn(1) atoms.
