NaSnS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Na(1) is bonded to six equivalent S(1) atoms to form NaS6 octahedra that share corners with six equivalent Sn(1)S6 octahedra, edges with six equivalent Na(1)S6 octahedra, and edges with six equivalent Sn(1)S6 octahedra. The corner-sharing octahedral tilt angles are 4°. Sn(1) is bonded to six equivalent S(1) atoms to form SnS6 octahedra that share corners with six equivalent Na(1)S6 octahedra, edges with six equivalent Na(1)S6 octahedra, and edges with six equivalent Sn(1)S6 octahedra. The corner-sharing octahedral tilt angles are 4°. S(1) is bonded to three equivalent Na(1) and three equivalent Sn(1) atoms to form a mixture of corner and edge-sharing SNa3Sn3 octahedra. The corner-sharing octahedra are not tilted.
