Title: Materials Data on Sm2FeGe4 by Materials Project

Abstract

Sm2FeGe4 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 10-coordinate geometry to one Fe and ten Ge atoms. The Sm–Fe bond length is 3.18 Å. There are a spread of Sm–Ge bond distances ranging from 3.07–3.21 Å. In the second Sm site, Sm is bonded in a 10-coordinate geometry to four equivalent Fe and ten Ge atoms. All Sm–Fe bond lengths are 3.36 Å. There are a spread of Sm–Ge bond distances ranging from 3.11–3.29 Å. Fe is bonded in a 5-coordinate geometry to five Sm and five Ge atoms. There are a spread of Fe–Ge bond distances ranging from 2.30–2.34 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six Sm, one Fe, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.70 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to six Sm and two equivalent Ge atoms. In the third Ge site, Ge is bonded in a 2-coordinate geometry to four Sm and two equivalent Fe atoms. In the fourth Gemore » site, Ge is bonded in a 2-coordinate geometry to four Sm and two equivalent Fe atoms.« less
