Title: Materials Data on Li3CuF6 by Materials Project

Abstract

Li3CuF6 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 7-coordinate geometry to seven F1- atoms. There are a spread of Li–F bond distances ranging from 1.98–2.57 Å. In the second 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 1.96–2.37 Å. In the third Li1+ site, Li1+ is bonded to five F1- atoms to form distorted LiF5 square pyramids that share corners with five CuF6 octahedra. The corner-sharing octahedra tilt angles range from 23–64°. There are a spread of Li–F bond distances ranging from 1.95–2.09 Å. There are two inequivalent Cu3+ sites. In the first Cu3+ site, Cu3+ is bonded to six F1- atoms to form CuF6 octahedra that share corners with six equivalent LiF5 square pyramids. All Cu–F bond lengths are 1.93 Å. In the second Cu3+ site, Cu3+ is bonded to six F1- atoms to form CuF6 octahedra that share corners with four equivalent LiF5 square pyramids. There is one shorter (1.91 Å) and five longer (1.92 Å) Cu–F bond length. There are seven inequivalentmore » F1- sites. In the first F1- site, F1- is bonded in a 5-coordinate geometry to four Li1+ and one Cu3+ atom. In the second F1- site, F1- is bonded to three Li1+ and one Cu3+ atom to form a mixture of corner and edge-sharing FLi3Cu trigonal pyramids. In the third F1- site, F1- is bonded in a trigonal non-coplanar geometry to two equivalent Li1+ and one Cu3+ atom. In the fourth F1- site, F1- is bonded to three Li1+ and one Cu3+ atom to form a mixture of distorted corner and edge-sharing FLi3Cu trigonal pyramids. In the fifth F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Li1+ and one Cu3+ atom. In the sixth F1- site, F1- is bonded to three Li1+ and one Cu3+ atom to form a mixture of distorted corner and edge-sharing FLi3Cu trigonal pyramids. In the seventh F1- site, F1- is bonded to three Li1+ and one Cu3+ atom to form a mixture of distorted corner and edge-sharing FLi3Cu trigonal pyramids.« less
