Materials Data on Sm5Pb3 by Materials Project
Sm5Pb3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 6-coordinate geometry to six equivalent Pb atoms. All Sm–Pb bond lengths are 3.32 Å. In the second Sm site, Sm is bonded in a 5-coordinate geometry to five equivalent Pb atoms. There are a spread of Sm–Pb bond distances ranging from 3.19–3.69 Å. Pb is bonded in a 9-coordinate geometry to nine Sm atoms.
