Materials Data on LiSiAg2 by Materials Project

Abstract

LiAg2Si crystallizes in the cubic F-43m space group. The structure is three-dimensional. Li1+ is bonded in a body-centered cubic geometry to four equivalent Ag+1.50+ and four equivalent Si4- atoms. All Li–Ag bond lengths are 2.76 Å. All Li–Si bond lengths are 2.76 Å. There are two inequivalent Ag+1.50+ sites. In the first Ag+1.50+ site, Ag+1.50+ is bonded in a body-centered cubic geometry to four equivalent Ag+1.50+ and four equivalent Si4- atoms. All Ag–Ag bond lengths are 2.76 Å. All Ag–Si bond lengths are 2.76 Å. In the second Ag+1.50+ site, Ag+1.50+ is bonded in a 4-coordinate geometry to four equivalent Li1+ and four equivalent Ag+1.50+ atoms. Si4- is bonded in a distorted body-centered cubic geometry to four equivalent Li1+ and four equivalent Ag+1.50+ atoms.
