AuPbO2 crystallizes in the triclinic P-1 space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second Au site, Au(2) is bonded in a linear geometry to two equivalent O(2) atoms. Pb(1) is bonded in a 5-coordinate geometry to two equivalent O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Au(1) and three equivalent Pb(1) atoms to form distorted OPb3Au tetrahedra that share corners with three equivalent O(1)Pb3Au tetrahedra, corners with four equivalent O(2)Pb2Au2 tetrahedra, edges with two equivalent O(2)Pb2Au2 tetrahedra, and edges with two equivalent O(1)Pb3Au tetrahedra. In the second O site, O(2) is bonded to one Au(1), one Au(2), and two equivalent Pb(1) atoms to form distorted OPb2Au2 tetrahedra that share corners with four equivalent O(2)Pb2Au2 tetrahedra, corners with four equivalent O(1)Pb3Au tetrahedra, and edges with two equivalent O(1)Pb3Au tetrahedra.
AuPbO2 crystallizes in the triclinic P-1 space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Au(1)-O(1) bond lengths are 2.01 Å. Both Au(1)-O(2) bond lengths are 2.03 Å. In the second Au site, Au(2) is bonded in a linear geometry to two equivalent O(2) atoms. Both Au(2)-O(2) bond lengths are 2.02 Å. Pb(1) is bonded in a 5-coordinate geometry to two equivalent O(2) and three equivalent O(1) atoms. There is one shorter (2.43 Å) and one longer (2.71 Å) Pb(1)-O(2) bond length. There are a spread of Pb(1)-O(1) bond distances ranging from 2.29-2.47 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Au(1) and three equivalent Pb(1) atoms to form distorted OPb3Au tetrahedra that share corners with three equivalent O(1)Pb3Au tetrahedra, corners with four equivalent O(2)Pb2Au2 tetrahedra, edges with two equivalent O(2)Pb2Au2 tetrahedra, and edges with two equivalent O(1)Pb3Au tetrahedra.
