Materials Data on Li2Cu5F12 by Materials Project
Abstract
Li2Cu5F12 crystallizes in the monoclinic P2/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 LiF6 octahedra that share corners with eight equivalent CuF6 octahedra, edges with two equivalent CuF6 octahedra, and edges with two equivalent LiF4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 47–51°. There are a spread of Li–F bond distances ranging from 1.95–2.31 Å. In the second Li1+ site, Li1+ is bonded to four F1- atoms to form distorted LiF4 trigonal pyramids that share corners with four CuF6 octahedra, edges with two equivalent LiF6 octahedra, and edges with two equivalent CuF6 octahedra. The corner-sharing octahedra tilt angles range from 58–65°. There is two shorter (1.87 Å) and two longer (1.91 Å) Li–F bond length. There are three inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to six F1- atoms to form a mixture of edge and corner-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 46–50°. There are four shorter (1.96 Å) and two longer (2.30 Å) Cu–F bond lengths. In the second Cu2+ site, Cu2+ is bonded to six F1- atoms to formmore »
