Materials Data on Li3Fe3OF7 by Materials Project
Abstract
Li3Fe3OF7 is Spinel-derived structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four F1- atoms to form LiF4 tetrahedra that share corners with three equivalent LiF6 octahedra and corners with nine FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 53–64°. There are a spread of Li–F bond distances ranging from 1.99–2.03 Å. In the second Li1+ site, Li1+ is bonded to six F1- atoms to form LiF6 octahedra that share corners with six LiF4 tetrahedra and edges with six FeOF5 octahedra. There are a spread of Li–F bond distances ranging from 2.04–2.18 Å. In the third Li1+ site, Li1+ is bonded to one O2- and three F1- atoms to form LiOF3 tetrahedra that share corners with three equivalent LiF6 octahedra and corners with nine FeOF5 octahedra. The corner-sharing octahedra tilt angles range from 51–61°. The Li–O bond length is 1.95 Å. There are a spread of Li–F bond distances ranging from 1.94–2.04 Å. There are three inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded to one O2- and five F1- atoms to form FeOF5 octahedra that sharemore »
