Li5BiS4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four S2- atoms to form LiS4 tetrahedra that share a cornercorner with one BiS6 octahedra, corners with ten LiS4 tetrahedra, edges with two equivalent BiS6 octahedra, and edges with three LiS4 tetrahedra. The corner-sharing octahedral tilt angles are 57°. There are a spread of Li–S bond distances ranging from 2.45–2.58 Å. In the second Li1+ site, Li1+ is bonded to four S2- atoms to form LiS4 tetrahedra that share a cornercorner with one BiS6 octahedra, corners with ten LiS4 tetrahedra, edges with two equivalent BiS6 octahedra, and edges with three LiS4 tetrahedra.
