The material structure described by Pb3O4 crystallizes in the tetragonal P4_2/mbc space group. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 3-coordinate geometry to one O(1) and two equivalent O(2) atoms. In the second Pb site, Pb(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing PbO6 octahedra. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to one Pb(2) and two equivalent Pb(1) atoms. In the second O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Pb(1) and two equivalent Pb(2) atoms. is represented by the CIF card [CIF]
