Materials Data on AgPbO2 by Materials Project

Abstract

AgPbO2 crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. there are two inequivalent Ag2+ sites. In the first Ag2+ site, Ag2+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.09 Å. In the second Ag2+ site, Ag2+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.10 Å. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded to six O2- atoms to form edge-sharing PbO6 octahedra. There are two shorter (2.19 Å) and four longer (2.31 Å) Pb–O bond lengths. In the second Pb2+ site, Pb2+ is bonded to six O2- atoms to form edge-sharing PbO6 octahedra. There are four shorter (2.51 Å) and two longer (2.55 Å) Pb–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to one Ag2+ and three Pb2+ atoms to form a mixture of distorted edge and corner-sharing OAgPb3 tetrahedra. In the second O2- site, O2- is bonded to one Ag2+ and three Pb2+ atoms to form a mixture of distorted edge and corner-sharing OAgPb3 tetrahedra.
