Materials Data on Sm2Ge2Rh by Materials Project

Abstract

Sm2RhGe2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 11-coordinate geometry to four equivalent Rh and seven Ge atoms. There are a spread of Sm–Rh bond distances ranging from 3.08–3.36 Å. There are a spread of Sm–Ge bond distances ranging from 3.06–3.36 Å. In the second Sm site, Sm is bonded in a 8-coordinate geometry to two equivalent Rh and six Ge atoms. Both Sm–Rh bond lengths are 3.11 Å. There are a spread of Sm–Ge bond distances ranging from 3.09–3.17 Å. Rh is bonded in a 10-coordinate geometry to six Sm and four Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.54–2.74 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to six Sm, three equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.86 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to seven Sm, one Rh, and one Ge atom. The Ge–Ge bond length is 2.66 Å.
