Materials Data on Dy2Pd2Pb by Materials Project

Dy2Pd2Pb crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Dy is bonded in a 6-coordinate geometry to six equivalent Pd and four equivalent Pb atoms. There are two shorter (2.91 Å) and four longer (2.99 Å) Dy–Pd bond lengths. All Dy–Pb bond lengths are 3.46 Å. Pd is bonded in a 6-coordinate geometry to six equivalent Dy, one Pd, and two equivalent Pb atoms. The Pd–Pd bond length is 2.83 Å. Both Pd–Pb bond lengths are 3.15 Å. Pb is bonded to eight equivalent Dy and four equivalent Pd atoms to form a mixture of corner and face-sharing PbDy8Pd4 cuboctahedra.

Materials Data on DyPdPb by Materials Project

DyPdPb crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Dy is bonded in a 11-coordinate geometry to five Pd and six equivalent Pb atoms. There are four shorter (3.09 Å) and one longer (3.15 Å) Dy–Pd bond lengths. There are two shorter (3.27 Å) and four longer (3.39 Å) Dy–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 Dy and three equivalent Pb atoms. All Pd–Pb bond lengths are 2.92 Å. In the second Pd site, Pd is bonded in a 9-coordinate geometry to three equivalent Dy and six equivalent Pb atoms. All Pd–Pb bond lengths are 2.85 Å. Pb is bonded in a distorted q6 geometry to six equivalent Dy and four Pd atoms.
