Materials Data on Li7Sb2S by Materials Project

Li7Sb2S crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are seven inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 1-coordinate geometry to three Sb+2.50- and one S2- atom. There are a spread of Li–Sb bond distances ranging from 2.92–3.31 Å. The Li–S bond length is 2.41 Å. In the second Li1+ site, Li1+ is bonded to three Sb+2.50- and one S2- atom to form a mixture of distorted edge and corner-sharing LiSb3S tetrahedra. There are a spread of Li–Sb bond distances ranging from 2.82–2.96 Å. The Li–S bond length is 2.44 Å. In the third Li1+ site, Li1+ is bonded to three Sb+2.50- and one S2- atom to form a mixture of edge and corner-sharing LiSb3S tetrahedra.
