Materials Data on LiUAsO6 by Materials Project
Abstract
LiUAsO6 crystallizes in the triclinic P-1 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 two equivalent UO6 octahedra and corners with three AsO4 tetrahedra. The corner-sharing octahedra tilt angles range from 60–77°. There are a spread of Li–O bond distances ranging from 2.00–2.10 Å. In the second Li1+ site, Li1+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 1.98–2.81 Å. There are two inequivalent U6+ sites. In the first U6+ site, U6+ is bonded to six O2- atoms to form UO6 octahedra that share corners with two equivalent LiO4 tetrahedra and corners with four AsO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.81–2.34 Å. In the second U6+ site, U6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of U–O bond distances ranging from 1.83–2.44 Å. There are two inequivalent As5+ sites. In the first As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with two equivalentmore »
