Title: Materials Data on Rb3U3Ge2O13 by Materials Project

Abstract

Rb3U3Ge2O13 crystallizes in the hexagonal P-62c space group. The structure is three-dimensional. Rb1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Rb–O bond distances ranging from 3.05–3.55 Å. U5+ is bonded to six O2- atoms to form UO6 octahedra that share corners with four equivalent UO6 octahedra and corners with two equivalent GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 6–35°. There are a spread of U–O bond distances ranging from 2.13–2.22 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with three equivalent UO6 octahedra and a cornercorner with one GeO4 tetrahedra. The corner-sharing octahedral tilt angles are 25°. There is three shorter (1.76 Å) and one longer (1.77 Å) Ge–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to three equivalent Rb1+, one U5+, and one Ge4+ atom. In the second O2- site, O2- is bonded in a linear geometry to three equivalent Rb1+ and two equivalent U5+ atoms. In the third O2- site, O2- is bonded in a linear geometry to three equivalent Rb1+ and two equivalent Ge4+ atoms. In themore » fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Rb1+ and two equivalent U5+ atoms.« less
