Materials Data on Li2AgSb by Materials Project
Li2AgSb is alpha bismuth trifluoride-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four equivalent Sb3- atoms to form corner-sharing LiSb4 tetrahedra. All Li–Sb bond lengths are 2.88 Å. In the second Li1+ site, Li1+ is bonded to four equivalent Ag1+ atoms to form distorted corner-sharing LiAg4 tetrahedra. All Li–Ag bond lengths are 2.88 Å. Ag1+ is bonded in a body-centered cubic geometry to four equivalent Li1+ and four equivalent Sb3- atoms. All Ag–Sb bond lengths are 2.88 Å. Sb3- is bonded in a 8-coordinate geometry to four equivalent Li1+ and four equivalent Ag1+ atoms.
