Materials Data on Li5AuO4 by Materials Project

Abstract

Li5AuO4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a distorted linear geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 1.92–2.50 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form a mixture of edge and corner-sharing LiO4 trigonal pyramids. There are a spread of Li–O bond distances ranging from 1.98–2.04 Å. In the third Li1+ site, Li1+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.96–2.69 Å. Au3+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.04 Å) and two longer (2.06 Å) Au–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to five Li1+ and one Au3+ atom. In the second O2- site, O2- is bonded in a 8-coordinate geometry to seven Li1+ and one Au3+ atom.
