The crystal structure described by Pb2O3 crystallizes in the orthorhombic Pmn2_1 space group. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to one O(3), three equivalent O(1), and three equivalent O(2) atoms to form distorted edge-sharing PbO7 pentagonal bipyramids. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to three equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Pb(1) atoms. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to three equivalent Pb(1) atoms. In the third O site, O(3) is bonded to one Pb(1) and three equivalent Pb(2) atoms to form corner-sharing OPb4 trigonal pyramids. is represented by the CIF file [CIF]
