Materials Data on PrPbAu by Materials Project

PrAuPb is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pr is bonded to six equivalent Au and six equivalent Pb atoms to form a mixture of edge and face-sharing PrPb6Au6 cuboctahedra. All Pr–Au bond lengths are 3.44 Å. All Pr–Pb bond lengths are 3.44 Å. Au is bonded in a 9-coordinate geometry to six equivalent Pr and three equivalent Pb atoms. All Au–Pb bond lengths are 2.83 Å. Pb is bonded in a 9-coordinate geometry to six equivalent Pr and three equivalent Au atoms.
