The material described by PbO2 is Baddeleyite-like structured and crystallizes in the orthorhombic Pnma space group. Pb(1) is bonded to three equivalent O(2) and four equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing PbO7 hexagonal pyramids. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal non-coplanar geometry to three equivalent Pb(1) atoms. In the second O site, O(1) is bonded to four equivalent Pb(1) atoms to form a mixture of edge and corner-sharing OPb4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
