Title: Materials Data on Rb2GeF6 by Materials Project

Abstract

Rb2GeF6 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to twelve F1- atoms to form RbF12 cuboctahedra that share corners with six equivalent RbF12 cuboctahedra, corners with three equivalent GeF6 octahedra, faces with eight RbF12 cuboctahedra, and faces with three equivalent GeF6 octahedra. The corner-sharing octahedral tilt angles are 16°. There are a spread of Rb–F bond distances ranging from 3.06–3.29 Å. In the second Rb1+ site, Rb1+ is bonded to twelve F1- atoms to form distorted RbF12 cuboctahedra that share corners with twelve equivalent RbF12 cuboctahedra, faces with six equivalent RbF12 cuboctahedra, and faces with four equivalent GeF6 octahedra. There are a spread of Rb–F bond distances ranging from 3.00–3.11 Å. Ge4+ is bonded to six F1- atoms to form GeF6 octahedra that share corners with three equivalent RbF12 cuboctahedra and faces with seven RbF12 cuboctahedra. All Ge–F bond lengths are 1.84 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to four Rb1+ and one Ge4+ atom. In the second F1- site, F1- is bonded in a distorted single-bond geometrymore » to four Rb1+ and one Ge4+ atom.« less
