The material described by Au2Pb is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. Au(1) is bonded to six equivalent Au(1) and six equivalent Pb(1) atoms to form a mixture of edge, face, and corner-sharing AuPb6Au6 cuboctahedra. Pb(1) is bonded in a 16-coordinate geometry to twelve equivalent Au(1) and four equivalent Pb(1) atoms. is represented by the CIF card [CIF]
