Materials Data on LiAgF2 by Materials Project

Abstract

LiAgF2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded to five F1- atoms to form a mixture of distorted corner and edge-sharing LiF5 square pyramids. There are four shorter (1.97 Å) and one longer (2.64 Å) Li–F bond lengths. Ag1+ is bonded in a 5-coordinate geometry to five F1- atoms. There are a spread of Ag–F bond distances ranging from 2.42–2.50 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 5-coordinate geometry to two equivalent Li1+ and three equivalent Ag1+ atoms. In the second F1- site, F1- is bonded in a 2-coordinate geometry to three equivalent Li1+ and two equivalent Ag1+ atoms.
