Materials Data on PtPbF6 by Materials Project
PtPbF6 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Pt4+ is bonded to six equivalent F1- atoms to form PtF6 octahedra that share corners with six equivalent PbF12 cuboctahedra and faces with two equivalent PbF12 cuboctahedra. All Pt–F bond lengths are 1.97 Å. Pb2+ is bonded to twelve equivalent F1- atoms to form PbF12 cuboctahedra that share corners with six equivalent PtF6 octahedra, edges with six equivalent PbF12 cuboctahedra, and faces with two equivalent PtF6 octahedra. The corner-sharing octahedral tilt angles are 41°. All Pb–F bond lengths are 2.78 Å. F1- is bonded in a distorted single-bond geometry to one Pt4+ and two equivalent Pb2+ atoms.
