Materials Data on Li6SbS2 by Materials Project

Abstract

Li6SbS2 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to two equivalent Sb2- and two equivalent S2- atoms to form a mixture of edge and corner-sharing LiSb2S2 tetrahedra. Both Li–Sb bond lengths are 2.83 Å. Both Li–S bond lengths are 2.48 Å. In the second Li1+ site, Li1+ is bonded to two equivalent Sb2- and two equivalent S2- atoms to form a mixture of edge and corner-sharing LiSb2S2 tetrahedra. There are one shorter (2.83 Å) and one longer (2.84 Å) Li–Sb bond lengths. There are one shorter (2.47 Å) and one longer (2.48 Å) Li–S bond lengths. In the third Li1+ site, Li1+ is bonded to four equivalent S2- atoms to form a mixture of edge and corner-sharing LiS4 tetrahedra. There are a spread of Li–S bond distances ranging from 2.47–2.49 Å. Sb2- is bonded in a body-centered cubic geometry to eight Li1+ atoms. S2- is bonded in a body-centered cubic geometry to eight Li1+ atoms.
