Materials Data on Pt(PbO2)2 by Materials Project

Abstract

Pb2PtO4 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Pt4+ is bonded to six O2- atoms to form edge-sharing PtO6 octahedra. There are two shorter (2.04 Å) and four longer (2.07 Å) Pt–O bond lengths. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 4-coordinate geometry to three O2- atoms. There are two shorter (2.24 Å) and one longer (2.37 Å) Pb–O bond lengths. In the second Pb2+ site, Pb2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.23–2.69 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Pt4+ and two equivalent Pb2+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Pt4+ and one Pb2+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to one Pt4+ and two Pb2+ atoms.
