Materials Data on Sm3Rh2 by Materials Project
Sm3Rh2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are three inequivalent Sm sites. In the first Sm site, Sm is bonded in a 5-coordinate geometry to five equivalent Rh atoms. There are a spread of Sm–Rh bond distances ranging from 2.88–3.29 Å. In the second Sm site, Sm is bonded in an octahedral geometry to six equivalent Rh atoms. All Sm–Rh bond lengths are 3.02 Å. In the third Sm site, Sm is bonded in a 6-coordinate geometry to six equivalent Rh atoms. There are three shorter (2.90 Å) and three longer (3.11 Å) Sm–Rh bond lengths. Rh is bonded in a 8-coordinate geometry to eight Sm atoms.
