Materials Data on Yb5Pb3 by Materials Project

Yb5Pb3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Yb sites. In the first Yb site, Yb is bonded in a 5-coordinate geometry to five equivalent Pb atoms. There are a spread of Yb–Pb bond distances ranging from 3.25–3.60 Å. In the second Yb site, Yb is bonded in a 6-coordinate geometry to six equivalent Pb atoms. All Yb–Pb bond lengths are 3.39 Å. Pb is bonded in a 9-coordinate geometry to nine Yb atoms.

Materials Data on Yb3Pb by Materials Project

Yb3Pb crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Yb is bonded in a distorted see-saw-like geometry to four equivalent Pb atoms. There are two shorter (3.46 Å) and two longer (3.56 Å) Yb–Pb bond lengths. Pb is bonded to twelve equivalent Yb atoms to form a mixture of corner and face-sharing PbYb12 cuboctahedra.
