Materials Data on Li2Cu3F9 by Materials Project
Abstract
Li2Cu3F9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to five F1- atoms to form distorted LiF5 square pyramids that share corners with two equivalent CuF6 octahedra, an edgeedge with one CuF6 octahedra, and an edgeedge with one LiF5 square pyramid. The corner-sharing octahedra tilt angles range from 15–26°. There are a spread of Li–F bond distances ranging from 1.97–2.24 Å. In the second 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 1.87–2.02 Å. There are three inequivalent Cu+2.33+ sites. In the first Cu+2.33+ site, Cu+2.33+ is bonded to six F1- atoms to form distorted CuF6 octahedra that share corners with two equivalent CuF6 octahedra, corners with two equivalent LiF5 square pyramids, an edgeedge with one CuF6 octahedra, and an edgeedge with one LiF5 square pyramid. The corner-sharing octahedra tilt angles range from 44–55°. There are a spread of Cu–F bond distances ranging from 1.86–2.38 Å. In the second Cu+2.33+ site, Cu+2.33+ is bonded to six F1- atoms to form a mixture of edge and corner-sharing CuF6 octahedra.more »
