Materials Data on YbCuPb by Materials Project

YbCuPb is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Yb is bonded to six equivalent Cu and six equivalent Pb atoms to form a mixture of edge and face-sharing YbCu6Pb6 cuboctahedra. All Yb–Cu bond lengths are 3.26 Å. All Yb–Pb bond lengths are 3.26 Å. Cu is bonded in a 3-coordinate geometry to six equivalent Yb and three equivalent Pb atoms. All Cu–Pb bond lengths are 2.72 Å. Pb is bonded in a 9-coordinate geometry to six equivalent Yb and three equivalent Cu atoms.
