Materials Data on Li2FeF6 by Materials Project
Abstract
Li2FeF6 is beta Vanadium nitride-derived structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are four inequivalent Li sites. In the first Li site, Li is bonded to six F atoms to form LiF6 octahedra that share corners with four equivalent FeF6 octahedra, an edgeedge with one FeF6 octahedra, and edges with three LiF6 octahedra. The corner-sharing octahedra tilt angles range from 43–49°. There are a spread of Li–F bond distances ranging from 2.00–2.15 Å. In the second Li site, Li is bonded to six F atoms to form LiF6 octahedra that share corners with four equivalent FeF6 octahedra, an edgeedge with one FeF6 octahedra, and edges with three LiF6 octahedra. The corner-sharing octahedra tilt angles range from 43–50°. There are a spread of Li–F bond distances ranging from 1.99–2.17 Å. In the third Li site, Li is bonded to six F atoms to form LiF6 octahedra that share corners with four equivalent FeF6 octahedra, an edgeedge with one FeF6 octahedra, and edges with three LiF6 octahedra. The corner-sharing octahedra tilt angles range from 44–50°. There are a spread of Li–F bond distances ranging from 1.94–2.18 Å. In the fourth Li site, Li is bondedmore »
