Materials Data on Rb2SbCl6 by Materials Project

Abstract

Rb2SbCl6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb is bonded to twelve equivalent Cl atoms to form RbCl12 cuboctahedra that share corners with twelve equivalent RbCl12 cuboctahedra, faces with six equivalent RbCl12 cuboctahedra, and faces with four equivalent SbCl6 octahedra. All Rb–Cl bond lengths are 3.71 Å. Sb is bonded to six equivalent Cl atoms to form SbCl6 octahedra that share faces with eight equivalent RbCl12 cuboctahedra. All Sb–Cl bond lengths are 2.54 Å. Cl is bonded to four equivalent Rb and one Sb atom to form a mixture of distorted face, edge, and corner-sharing ClRb4Sb square pyramids.
