Materials Data on SmPbAu by Materials Project
SmAuPb is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sm is bonded to six equivalent Au and six equivalent Pb atoms to form a mixture of edge and face-sharing SmPb6Au6 cuboctahedra. All Sm–Au bond lengths are 3.39 Å. All Sm–Pb bond lengths are 3.39 Å. Au is bonded in a 9-coordinate geometry to six equivalent Sm and three equivalent Pb atoms. All Au–Pb bond lengths are 2.82 Å. Pb is bonded in a 9-coordinate geometry to six equivalent Sm and three equivalent Au atoms.
