Materials Data on Sm2Ge5Rh3 by Materials Project

Abstract

Sm2Rh3Ge5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Sm is bonded in a 1-coordinate geometry to eight Ge atoms. There are a spread of Sm–Ge bond distances ranging from 3.03–3.32 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.52–2.73 Å. In the second Rh site, Rh is bonded in a 5-coordinate geometry to five Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.42–2.53 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Sm, three Rh, and two Ge atoms. Both Ge–Ge bond lengths are 2.69 Å. In the second Ge site, Ge is bonded in a 3-coordinate geometry to three Rh and two equivalent Ge atoms. In the third Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Sm and four equivalent Rh atoms. In the fourth Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Sm, three Rh, and two equivalent Ge atoms.
