Materials Data on Rb2SnF6 by Materials Project
Rb2SnF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent F1- atoms to form RbF12 cuboctahedra that share corners with twelve equivalent RbF12 cuboctahedra, faces with six equivalent RbF12 cuboctahedra, and faces with four equivalent SnF6 octahedra. All Rb–F bond lengths are 3.21 Å. Sn4+ is bonded to six equivalent F1- atoms to form SnF6 octahedra that share faces with eight equivalent RbF12 cuboctahedra. All Sn–F bond lengths are 2.00 Å. F1- is bonded in a distorted single-bond geometry to four equivalent Rb1+ and one Sn4+ atom.
