The crystal structure described by LiNbS2 is Caswellsilverite-like structured and crystallizes in the hexagonal P6_3/mmc space group. Li(1) is bonded to six equivalent S(1) atoms to form LiS6 octahedra that share corners with twelve equivalent Nb(1)S6 pentagonal pyramids, edges with six equivalent Li(1)S6 octahedra, and faces with two equivalent Nb(1)S6 pentagonal pyramids. Nb(1) is bonded to six equivalent S(1) atoms to form distorted NbS6 pentagonal pyramids that share corners with twelve equivalent Li(1)S6 octahedra, edges with six equivalent Nb(1)S6 pentagonal pyramids, and faces with two equivalent Li(1)S6 octahedra. The corner-sharing octahedral tilt angles are 45°. S(1) is bonded to three equivalent Li(1) and three equivalent Nb(1) atoms to form a mixture of distorted corner, edge, and face-sharing SLi3Nb3 pentagonal pyramids. is represented by the CIF file [CIF]
