The material described by AuPb2 is Khatyrkite structured and crystallizes in the tetragonal I4/mcm space group. Au(1) is bonded in a distorted q6 geometry to two equivalent Au(1) and eight equivalent Pb(1) atoms. Pb(1) is bonded in a 7-coordinate geometry to four equivalent Au(1) and three equivalent Pb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
