Materials Data on Li5SbS4 by Materials Project

Abstract

Li5SbS4 crystallizes in the orthorhombic Cmc2_1 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 a mixture of distorted corner, edge, and face-sharing LiS4 tetrahedra. There are a spread of Li–S bond distances ranging from 2.47–2.64 Å. In the second Li1+ site, Li1+ is bonded to four S2- atoms to form a mixture of distorted corner, edge, and face-sharing LiS4 tetrahedra. There are a spread of Li–S bond distances ranging from 2.45–2.64 Å. In the third Li1+ site, Li1+ is bonded to four S2- atoms to form a mixture of distorted corner and edge-sharing LiS4 trigonal pyramids. There are a spread of Li–S bond distances ranging from 2.41–3.02 Å. Sb3+ is bonded in a distorted trigonal non-coplanar geometry to three S2- atoms. There are two shorter (2.47 Å) and one longer (2.49 Å) Sb–S bond lengths. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded to four Li1+ and one Sb3+ atom to form distorted corner-sharing SLi4Sb trigonal bipyramids. In the second S2- site, S2- is bonded in a 8-coordinate geometry to eight Li1+ atoms. In the third S2- site, S2- is bonded in a 5-coordinate geometry to four Li1+ and one Sb3+ atom.
