Materials Data on Li2SiAu by Materials Project

Abstract

Li2AuSi 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 Si4- atoms to form corner-sharing LiSi4 tetrahedra. All Li–Si bond lengths are 2.64 Å. In the second Li1+ site, Li1+ is bonded to four equivalent Au2+ atoms to form distorted corner-sharing LiAu4 tetrahedra. All Li–Au bond lengths are 2.64 Å. Au2+ is bonded in a body-centered cubic geometry to four equivalent Li1+ and four equivalent Si4- atoms. All Au–Si bond lengths are 2.64 Å. Si4- is bonded in a body-centered cubic geometry to four equivalent Li1+ and four equivalent Au2+ atoms.
