Materials Data on LiAg2F4 by Materials Project

Abstract

LiAg2F4 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. Li1+ is bonded to four equivalent F1- atoms to form distorted LiF4 tetrahedra that share corners with four equivalent AgF4 trigonal pyramids. All Li–F bond lengths are 1.90 Å. There are two inequivalent Ag+1.50+ sites. In the first Ag+1.50+ site, Ag+1.50+ is bonded in a 4-coordinate geometry to four equivalent F1- atoms. All Ag–F bond lengths are 2.26 Å. In the second Ag+1.50+ site, Ag+1.50+ is bonded to four equivalent F1- atoms to form distorted AgF4 trigonal pyramids that share corners with four equivalent LiF4 tetrahedra. All Ag–F bond lengths are 2.19 Å. F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two Ag+1.50+ atoms.
