Materials Data on Li5SbS4 by Materials Project

Abstract

Li5SbS4 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four S2- atoms. There are a spread of Li–S bond distances ranging from 2.41–3.06 Å. In the second Li1+ site, Li1+ is bonded to four S2- atoms to form LiS4 tetrahedra that share corners with four equivalent SbS4 trigonal pyramids. There are two shorter (2.44 Å) and two longer (2.45 Å) Li–S bond lengths. Sb3+ is bonded to four S2- atoms to form distorted SbS4 trigonal pyramids that share corners with four equivalent LiS4 tetrahedra. There are two shorter (2.48 Å) and two longer (2.77 Å) Sb–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to five Li1+ and one Sb3+ atom. In the second S2- site, S2- is bonded in a 4-coordinate geometry to five Li1+ and one Sb3+ atom.
