Materials Data on LiAgF2 by Materials Project

Abstract

LiAgF2 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. Li1+ is bonded to four F1- atoms to form LiF4 tetrahedra that share corners with four equivalent LiF4 tetrahedra and corners with eight equivalent AgF4 tetrahedra. There are a spread of Li–F bond distances ranging from 1.88–1.90 Å. Ag1+ is bonded to four F1- atoms to form AgF4 tetrahedra that share corners with four equivalent AgF4 tetrahedra and corners with eight equivalent LiF4 tetrahedra. There are a spread of Ag–F bond distances ranging from 2.33–2.43 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 4-coordinate geometry to two equivalent Li1+ and two equivalent Ag1+ atoms. In the second F1- site, F1- is bonded in a 4-coordinate geometry to two equivalent Li1+ and two equivalent Ag1+ atoms.
