The structure described by LiS crystallizes in the tetragonal I-42m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to four equivalent S(1) atoms to form distorted corner-sharing LiS4 tetrahedra. In the second Li site, Li(2) is bonded to four equivalent S(1) atoms to form distorted corner-sharing LiS4 trigonal pyramids. S(1) is bonded in a 5-coordinate geometry to two equivalent Li(1), two equivalent Li(2), and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
