Materials Data on LiAgF2 by Materials Project

Abstract

LiAgF2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Li1+ is bonded to five F1- atoms to form edge-sharing LiF5 square pyramids. There are a spread of Li–F bond distances ranging from 1.98–2.02 Å. Ag1+ is bonded in a 3-coordinate geometry to four F1- atoms. There are a spread of Ag–F bond distances ranging from 2.19–2.97 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Li1+ and one Ag1+ atom. In the second F1- site, F1- is bonded in a 4-coordinate geometry to two equivalent Li1+ and three equivalent Ag1+ atoms.
