The structure described by Au2Pb crystallizes in the orthorhombic Pbcn space group. There are three inequivalent Au sites. In the first Au site, Au(1) is bonded in a 10-coordinate geometry to two equivalent Au(3), four equivalent Au(2), and four equivalent Pb(1) atoms. In the second Au site, Au(2) is bonded in a 9-coordinate geometry to two equivalent Au(1), two equivalent Au(2), two equivalent Au(3), and three equivalent Pb(1) atoms. In the third Au site, Au(3) is bonded to two equivalent Au(1), four equivalent Au(2), and six equivalent Pb(1) atoms to form a mixture of corner, face, and edge-sharing AuPb6Au6 cuboctahedra. Pb(1) is bonded in a 8-coordinate geometry to two equivalent Au(1), three equivalent Au(2), and three equivalent Au(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
