Materials Data on LiCu2F7 by Materials Project

Abstract

LiCu2F7 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a distorted trigonal planar geometry to three F1- atoms. There is two shorter (1.83 Å) and one longer (1.85 Å) Li–F bond length. In the second Li1+ site, Li1+ is bonded in a distorted trigonal planar geometry to three F1- atoms. There are a spread of Li–F bond distances ranging from 1.83–1.87 Å. There are four inequivalent Cu3+ sites. In the first Cu3+ site, Cu3+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 39–48°. There are a spread of Cu–F bond distances ranging from 1.85–2.03 Å. In the second Cu3+ site, Cu3+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 40–48°. There are a spread of Cu–F bond distances ranging from 1.87–2.02 Å. In the third Cu3+ site, Cu3+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 39–45°. There are a spread of Cu–F bond distances ranging from 1.82–2.02 Å. In the fourth Cu3+ site, Cu3+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 40–45°. There are a spread of Cu–F bond distances ranging from 1.84–2.00 Å. There are fourteen inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to two Cu3+ atoms. In the second F1- site, F1- is bonded in a bent 150 degrees geometry to two Cu3+ atoms. In the third F1- site, F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two Cu3+ atoms. In the fourth F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two Cu3+ atoms. In the fifth F1- site, F1- is bonded in a bent 120 degrees geometry to one Li1+ and one Cu3+ atom. In the sixth F1- site, F1- is bonded in a bent 120 degrees geometry to one Li1+ and one Cu3+ atom. In the seventh F1- site, F1- is bonded in a 2-coordinate geometry to two Cu3+ atoms. In the eighth F1- site, F1- is bonded in a 2-coordinate geometry to two Cu3+ atoms. In the ninth F1- site, F1- is bonded in a bent 120 degrees geometry to one Li1+ and one Cu3+ atom. In the tenth F1- site, F1- is bonded in a 2-coordinate geometry to two Cu3+ atoms. In the eleventh F1- site, F1- is bonded in a bent 120 degrees geometry to one Li1+ and one Cu3+ atom. In the twelfth F1- site, F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two Cu3+ atoms. In the thirteenth F1- site, F1- is bonded in a bent 150 degrees geometry to two Cu3+ atoms. In the fourteenth F1- site, F1- is bonded in a bent 150 degrees geometry to two Cu3+ atoms.
