Materials Data on BiPb by Materials Project

Abstract

Bi(Pb) is beta-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Pb is bonded to six equivalent Pb and six equivalent Bi atoms to form PbBi6Pb6 cuboctahedra that share corners with eighteen equivalent PbBi6Pb6 cuboctahedra, edges with six equivalent PbBi6Pb6 cuboctahedra, edges with twelve equivalent BiBi6Pb6 cuboctahedra, faces with eight equivalent PbBi6Pb6 cuboctahedra, and faces with twelve equivalent BiBi6Pb6 cuboctahedra. All Pb–Pb bond lengths are 3.52 Å. All Pb–Bi bond lengths are 3.61 Å.
