Materials Data on YbPdPb by Materials Project

YbPdPb crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Yb is bonded in a 11-coordinate geometry to five Pd and six equivalent Pb atoms. There are four shorter (3.11 Å) and one longer (3.17 Å) Yb–Pd bond lengths. There are two shorter (3.27 Å) and four longer (3.43 Å) Yb–Pb bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 9-coordinate geometry to six equivalent Yb and three equivalent Pb atoms. All Pd–Pb bond lengths are 2.91 Å. In the second Pd site, Pd is bonded in a 9-coordinate geometry to three equivalent Yb and six equivalent Pb atoms. All Pd–Pb bond lengths are 2.87 Å. Pb is bonded in a 10-coordinate geometry to six equivalent Yb and four Pd atoms.
