Materials Data on K2SBrCl6 by Materials Project

Abstract

K2SCl6Br crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of four hydrobromic acid molecules and one K2SCl6 framework. In the K2SCl6 framework, K1+ is bonded to twelve equivalent Cl1- atoms to form KCl12 cuboctahedra that share corners with twelve equivalent KCl12 cuboctahedra, faces with six equivalent KCl12 cuboctahedra, and faces with four equivalent SCl6 octahedra. All K–Cl bond lengths are 3.76 Å. S1- is bonded to six equivalent Cl1- atoms to form SCl6 octahedra that share faces with eight equivalent KCl12 cuboctahedra. All S–Cl bond lengths are 2.33 Å. Cl1- is bonded in a distorted single-bond geometry to four equivalent K1+ and one S1- atom.
