Materials Data on Rb3U2Ge2O11 by Materials Project
Abstract
Rb3U2Ge2O11 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Rb–O bond distances ranging from 2.87–3.40 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.81–3.49 Å. In the third Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Rb–O bond distances ranging from 2.90–3.42 Å. There are three inequivalent U+5.50+ sites. In the first U+5.50+ site, U+5.50+ is bonded to six O2- atoms to form UO6 octahedra that share corners with two UO6 octahedra and corners with four GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 37–43°. There are a spread of U–O bond distances ranging from 2.03–2.25 Å. In the second U+5.50+ site, U+5.50+ is bonded to six O2- atoms to form UO6 octahedra that share corners with two equivalent UO6 octahedra and corners with two equivalent GeO4 tetrahedra. The corner-sharing octahedral tilt angles are 43°. There are a spread ofmore »
