Materials Data on Sm5Ge3 by Materials Project
Sm5Ge3 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 Ge atoms. All Sm–Ge bond lengths are 3.16 Å. In the second Sm site, Sm is bonded in a 5-coordinate geometry to five equivalent Ge atoms. There are a spread of Sm–Ge bond distances ranging from 3.01–3.56 Å. Ge is bonded in a 9-coordinate geometry to nine Sm atoms.
