The crystal structure described by Pb3O4 crystallizes in the orthorhombic Pbam space group. There are three inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(3) atoms. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(3) atoms. In the third Pb site, Pb(3) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing PbO6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Pb(1) and two equivalent Pb(3) atoms. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Pb(2) and two equivalent Pb(3) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Pb(1), one Pb(2), and one Pb(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
