Materials Data on Ag5(PbO3)2 by Materials Project

Abstract

Ag5Pb2O6 crystallizes in the trigonal P31m space group. The structure is three-dimensional. there are three inequivalent Ag+1.20+ sites. In the first Ag+1.20+ site, Ag+1.20+ is bonded in a linear geometry to two O2- atoms. Both Ag–O bond lengths are 2.15 Å. In the second Ag+1.20+ site, Ag+1.20+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All Ag–O bond lengths are 2.33 Å. In the third Ag+1.20+ site, Ag+1.20+ is bonded in a trigonal non-coplanar geometry to three equivalent O2- atoms. All Ag–O bond lengths are 2.36 Å. Pb3+ is bonded to six O2- atoms to form edge-sharing PbO6 octahedra. All Pb–O bond lengths are 2.28 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two Ag+1.20+ and two equivalent Pb3+ atoms to form a mixture of corner and edge-sharing OAg2Pb2 tetrahedra. In the second O2- site, O2- is bonded to two Ag+1.20+ and two equivalent Pb3+ atoms to form a mixture of corner and edge-sharing OAg2Pb2 tetrahedra.
