Materials Data on Li4Co3OF11 by Materials Project
Abstract
Li4Co3OF11 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 7-coordinate geometry to one O2- and six F1- atoms. The Li–O bond length is 2.47 Å. There are a spread of Li–F bond distances ranging from 1.97–2.60 Å. In the second Li1+ site, Li1+ is bonded to six F1- atoms to form distorted LiF6 pentagonal pyramids that share corners with four CoF6 octahedra, edges with two CoF6 octahedra, and an edgeedge with one LiF6 pentagonal pyramid. The corner-sharing octahedra tilt angles range from 43–60°. There are a spread of Li–F bond distances ranging from 1.98–2.27 Å. In the third Li1+ site, Li1+ is bonded to six F1- atoms to form distorted LiF6 pentagonal pyramids that share corners with four CoF6 octahedra, edges with two CoF6 octahedra, and an edgeedge with one LiF6 pentagonal pyramid. The corner-sharing octahedra tilt angles range from 46–59°. There are a spread of Li–F bond distances ranging from 1.97–2.22 Å. In the fourth 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 1.96–2.57 Å.more »
