Materials Data on Rb3SbF6 by Materials Project

Abstract

Rb3SbF6 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a distorted hexagonal planar geometry to six F1- atoms. There are a spread of Rb–F bond distances ranging from 2.88–3.00 Å. In the second Rb1+ site, Rb1+ is bonded in a distorted hexagonal planar geometry to six F1- atoms. There are four shorter (2.86 Å) and two longer (3.09 Å) Rb–F bond lengths. In the third Rb1+ site, Rb1+ is bonded in a distorted hexagonal planar geometry to six F1- atoms. There are two shorter (2.86 Å) and four longer (2.96 Å) Rb–F bond lengths. Sb3+ is bonded in an octahedral geometry to six F1- atoms. There are four shorter (2.21 Å) and two longer (2.22 Å) Sb–F bond lengths. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a 4-coordinate geometry to three Rb1+ and one Sb3+ atom. In the second F1- site, F1- is bonded in a distorted rectangular see-saw-like geometry to three Rb1+ and one Sb3+ atom. In the third F1- site, F1- is bonded in a distorted rectangular see-saw-like geometry to three Rb1+ and one Sb3+ atom.
