Materials Data on Pb3O4 by Materials Project

Pb3O4 crystallizes in the tetragonal P4_2/mbc space group. The structure is three-dimensional. there are two inequivalent Pb+2.67+ sites. In the first Pb+2.67+ site, Pb+2.67+ is bonded to six O2- atoms to form edge-sharing PbO6 octahedra. There are two shorter (2.18 Å) and four longer (2.25 Å) Pb–O bond lengths. In the second Pb+2.67+ site, Pb+2.67+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.25–2.82 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to four Pb+2.67+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to three Pb+2.67+ atoms.
