The material described by AuPbO2 crystallizes in the monoclinic P2/m space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a linear geometry to two equivalent O(2) atoms. In the second Au site, Au(2) is bonded in a linear geometry to two equivalent O(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing PbO6 octahedra. In the second Pb site, Pb(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form edge-sharing PbO6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Au(2), one Pb(2), and two equivalent Pb(1) atoms to form a mixture of edge and corner-sharing OPb3Au tetrahedra. In the second O site, O(2) is bonded to one Au(1), one Pb(1), and two equivalent Pb(2) atoms to form a mixture of distorted edge and corner-sharing OPb3Au tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
