Materials Data on Li4UF8 by Materials Project
Abstract
Li4UF8 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six F1- atoms to form a mixture of edge and corner-sharing LiF6 octahedra. The corner-sharing octahedra tilt angles range from 17–61°. There are a spread of Li–F bond distances ranging from 1.97–2.29 Å. In the second Li1+ site, Li1+ is bonded to six F1- atoms to form a mixture of edge and corner-sharing LiF6 octahedra. The corner-sharing octahedra tilt angles range from 19–39°. There are a spread of Li–F bond distances ranging from 2.01–2.10 Å. U4+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of U–F bond distances ranging from 2.20–2.43 Å. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Li1+ and one U4+ atom. In the second F1- site, F1- is bonded in a trigonal non-coplanar geometry to two equivalent Li1+ and one U4+ atom. In the third F1- site, F1- is bonded in a distorted rectangular see-saw-like geometry to three Li1+ and one U4+ atom. In the fourth F1- site,more »
