Title: Materials Data on Li3U7(AsO7)5 by Materials Project

Abstract

Li3U7(AsO7)5 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 trigonal bipyramids that share corners with three UO6 octahedra and an edgeedge with one AsO4 tetrahedra. The corner-sharing octahedra tilt angles range from 0–50°. There are a spread of Li–O bond distances ranging from 1.85–2.53 Å. In the second Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.88–2.59 Å. In the third Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.90–2.64 Å. There are seven inequivalent U6+ sites. In the first U6+ site, U6+ is bonded to six O2- atoms to form UO6 octahedra that share a cornercorner with one UO7 pentagonal bipyramid, corners with four AsO4 tetrahedra, and a cornercorner with one LiO5 trigonal bipyramid. There are a spread of U–O bond distances ranging from 1.82–2.26 Å.
