Materials Data on PrCuPb by Materials Project
PrCuPb 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 Cu and six equivalent Pb atoms to form a mixture of edge and face-sharing PrCu6Pb6 cuboctahedra. All Pr–Cu bond lengths are 3.35 Å. All Pr–Pb bond lengths are 3.35 Å. Cu is bonded in a 3-coordinate geometry to six equivalent Pr and three equivalent Pb atoms. All Cu–Pb bond lengths are 2.69 Å. Pb is bonded in a 3-coordinate geometry to six equivalent Pr and three equivalent Cu atoms.
