Materials Data on Li2AgF5 by Materials Project

Abstract

Li2AgF5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Li–F bond distances ranging from 1.90–2.62 Å. In the second Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five F1- atoms. There are a spread of Li–F bond distances ranging from 1.88–2.36 Å. There are two inequivalent Ag3+ sites. In the first Ag3+ site, Ag3+ is bonded to six F1- atoms to form distorted corner-sharing AgF6 octahedra. The corner-sharing octahedral tilt angles are 73°. There are a spread of Ag–F bond distances ranging from 1.97–2.64 Å. In the second Ag3+ site, Ag3+ is bonded to six F1- atoms to form corner-sharing AgF6 octahedra. The corner-sharing octahedral tilt angles are 73°. There are a spread of Ag–F bond distances ranging from 1.96–2.47 Å. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal planar geometry to two equivalent Li1+ and one Ag3+ atom. In the second F1- site, F1- is bonded in a 4-coordinate geometry to three Li1+ and one Ag3+ atom. In the third F1- site, F1- is bonded in a 3-coordinate geometry to two Li1+ and one Ag3+ atom. In the fourth F1- site, F1- is bonded in a 2-coordinate geometry to two Li1+ and two Ag3+ atoms. In the fifth F1- site, F1- is bonded in a trigonal planar geometry to two equivalent Li1+ and one Ag3+ atom.
