Materials Data on LiAgF4 by Materials Project
LiAgF4 is Calcite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. Li1+ is bonded to six F1- atoms to form LiF6 octahedra that share corners with eight equivalent AgF6 octahedra and edges with two equivalent LiF6 octahedra. The corner-sharing octahedra tilt angles range from 52–55°. There are a spread of Li–F bond distances ranging from 2.02–2.14 Å. Ag3+ is bonded to six F1- atoms to form AgF6 octahedra that share corners with eight equivalent LiF6 octahedra and edges with two equivalent AgF6 octahedra. The corner-sharing octahedra tilt angles range from 52–55°. There are a spread of Ag–F bond distances ranging from 1.98–2.20 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a trigonal planar geometry to two equivalent Li1+ and one Ag3+ atom. In the second F1- site, F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two equivalent Ag3+ atoms. In the third F1- site, F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two equivalent Ag3+ atoms. In the fourth F1- site, F1- is bonded in a trigonal planar geometry to two equivalent Li1+ and one Ag3+ atom.
