Materials Data on BiPb3Au by Materials Project
BiPb3Au crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Au is bonded in a 9-coordinate geometry to one Au, six Pb, and two equivalent Bi atoms. The Au–Au bond length is 2.84 Å. There are two shorter (3.05 Å) and four longer (3.19 Å) Au–Pb bond lengths. Both Au–Bi bond lengths are 2.97 Å. There are two inequivalent Pb sites. In the first Pb site, Pb is bonded in a 2-coordinate geometry to one Au and one Bi atom. The Pb–Bi bond length is 3.44 Å. In the second Pb site, Pb is bonded in a 4-coordinate geometry to four equivalent Au atoms. Bi is bonded in a 2-coordinate geometry to two equivalent Au and two equivalent Pb atoms.
