Materials Data on Li2Fe3WO8 by Materials Project
Abstract
Li2WFe3O8 is Hausmannite-derived structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent WO6 octahedra and corners with nine FeO6 octahedra. The corner-sharing octahedra tilt angles range from 55–66°. There are a spread of Li–O bond distances ranging from 1.97–2.05 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with three equivalent WO6 octahedra, corners with three FeO6 octahedra, and edges with three FeO6 octahedra. The corner-sharing octahedra tilt angles range from 58–66°. There are a spread of Li–O bond distances ranging from 1.85–2.12 Å. W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six FeO6 octahedra, corners with six LiO4 tetrahedra, and edges with three FeO6 octahedra. The corner-sharing octahedra tilt angles range from 45–54°. There are a spread of W–O bond distances ranging from 1.93–2.08 Å. There are three inequivalent Fe+2.67+ sites. In the first Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form FeO6 octahedra thatmore »
