Materials Data on LiMn2F5 by Materials Project
Abstract
LiMn2F5 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 five F1- atoms to form LiF5 trigonal bipyramids that share corners with two equivalent MnF6 pentagonal pyramids, an edgeedge with one MnF6 octahedra, an edgeedge with one MnF6 pentagonal pyramid, and an edgeedge with one LiF5 trigonal bipyramid. There are a spread of Li–F bond distances ranging from 1.89–2.12 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 1.86–1.99 Å. There are four inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded in a 7-coordinate geometry to seven F1- atoms. There are a spread of Mn–F bond distances ranging from 2.09–2.41 Å. In the second Mn2+ site, Mn2+ is bonded to six F1- atoms to form distorted MnF6 pentagonal pyramids that share corners with six MnF6 octahedra, corners with two equivalent LiF5 trigonal bipyramids, and an edgeedge with one LiF5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 39–63°. There are a spread of Mn–F bond distances ranging from 2.08–2.29 Å. Inmore »
