Materials Data on Cs4U5O17 by Materials Project
Abstract
Cs4U5O17 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cs–O bond distances ranging from 2.99–3.57 Å. In the second Cs1+ site, Cs1+ is bonded to six O2- atoms to form CsO6 octahedra that share corners with four UO6 octahedra, corners with two equivalent UO7 pentagonal bipyramids, and edges with two equivalent CsO6 octahedra. The corner-sharing octahedra tilt angles range from 50–59°. There are a spread of Cs–O bond distances ranging from 2.94–3.15 Å. There are three inequivalent U6+ sites. In the first U6+ site, U6+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share corners with two equivalent UO6 octahedra, corners with four equivalent CsO6 octahedra, and edges with four UO6 octahedra. The corner-sharing octahedra tilt angles range from 34–55°. There are a spread of U–O bond distances ranging from 1.85–2.48 Å. In the second U6+ site, U6+ is bonded to six O2- atoms to form UO6 octahedra that share corners with three equivalent CsO6 octahedra, corners with three UO6 octahedra, a cornercorner with onemore »
