Materials Data on Cs2PbClF6 by Materials Project

Abstract

(Cs2PbF6)2Cl2 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of four hydrochloric acid molecules and one Cs2PbF6 framework. In the Cs2PbF6 framework, Cs is bonded to twelve equivalent F atoms to form CsF12 cuboctahedra that share corners with twelve equivalent CsF12 cuboctahedra, faces with six equivalent CsF12 cuboctahedra, and faces with four equivalent PbF6 octahedra. All Cs–F bond lengths are 3.54 Å. Pb is bonded to six equivalent F atoms to form PbF6 octahedra that share faces with eight equivalent CsF12 cuboctahedra. All Pb–F bond lengths are 2.12 Å. F is bonded in a single-bond geometry to four equivalent Cs and one Pb atom.
