Materials Data on Pb2O3 by Materials Project

Abstract

Pb2O3 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are two inequivalent Pb3+ sites. In the first Pb3+ site, Pb3+ is bonded to seven O2- atoms to form distorted edge-sharing PbO7 pentagonal bipyramids. There are a spread of Pb–O bond distances ranging from 2.29–2.36 Å. In the second Pb3+ site, Pb3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Pb–O bond distances ranging from 2.38–3.02 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to five Pb3+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to five Pb3+ atoms. In the third O2- site, O2- is bonded to four Pb3+ atoms to form distorted corner-sharing OPb4 trigonal pyramids.
