BiPb3Au crystallizes in the tetragonal P4_2/mnm space group. Au(1) is bonded in a 9-coordinate geometry to one Au(1), two equivalent Pb(2), four equivalent Pb(1), and two equivalent Bi(1) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(2) is bonded in a 2-coordinate geometry to one Au(1) and one Bi(1) atom. In the second Pb site, Pb(1) is bonded in a 4-coordinate geometry to four equivalent Au(1) atoms. Bi(1) is bonded in a 2-coordinate geometry to two equivalent Au(1) and two equivalent Pb(2) atoms.
