Title: Materials Data on Li3Cu2F7 by Materials Project

Abstract

Li3Cu2F7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four F1- atoms. There are a spread of Li–F bond distances ranging from 1.89–2.09 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 1.97–2.38 Å. In the third Li1+ site, Li1+ is bonded to five F1- atoms to form LiF5 square pyramids that share corners with four equivalent CuF6 octahedra. The corner-sharing octahedra tilt angles range from 36–71°. There are a spread of Li–F bond distances ranging from 1.92–2.15 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to six F1- atoms to form distorted CuF6 octahedra that share corners with four equivalent LiF5 square pyramids and an edgeedge with one CuF6 octahedra. There are a spread of Cu–F bond distances ranging from 1.93–2.56 Å. In the second Cu2+ site, Cu2+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Cu–F bond distances ranging from 1.88–2.61 Å. There aremore » seven inequivalent F1- sites. In the first F1- site, F1- is bonded in a 4-coordinate geometry to three Li1+ and one Cu2+ atom. In the second F1- site, F1- is bonded in a 5-coordinate geometry to three Li1+ and two equivalent Cu2+ atoms. In the third F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to two Li1+ and one Cu2+ atom. In the fourth F1- site, F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two Cu2+ atoms. In the fifth F1- site, F1- is bonded in a 4-coordinate geometry to two Li1+ and two Cu2+ atoms. In the sixth F1- site, F1- is bonded in a distorted bent 120 degrees geometry to one Li1+ and two equivalent Cu2+ atoms. In the seventh F1- site, F1- is bonded in a distorted rectangular see-saw-like geometry to two Li1+ and two Cu2+ atoms.« less
