Materials Data on Li2CuF5 by Materials Project
Abstract
Li2CuF5 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 to six F1- atoms to form distorted LiF6 octahedra that share corners with two equivalent LiF6 octahedra, corners with three CuF6 octahedra, an edgeedge with one LiF6 octahedra, and edges with two equivalent CuF6 octahedra. The corner-sharing octahedra tilt angles range from 49–58°. There are a spread of Li–F bond distances ranging from 1.92–2.34 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 1.87–2.33 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 two equivalent LiF6 octahedra, corners with two equivalent CuF6 octahedra, and edges with four equivalent LiF6 octahedra. The corner-sharing octahedra tilt angles range from 49–55°. There are a spread of Cu–F bond distances ranging from 1.90–1.99 Å. In the second Cu3+ site, Cu3+ is bonded to six F1- atoms to form CuF6 octahedra that share corners with two equivalent CuF6 octahedra and corners with fourmore »
