Materials Data on SmGePd by Materials Project

Abstract

SmPdGe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Sm sites. In the first Sm site, Sm is bonded in a 12-coordinate geometry to six Pd and six Ge atoms. There are a spread of Sm–Pd bond distances ranging from 3.05–3.18 Å. There are a spread of Sm–Ge bond distances ranging from 3.17–3.30 Å. In the second Sm site, Sm is bonded in a 12-coordinate geometry to six Pd and six Ge atoms. There are a spread of Sm–Pd bond distances ranging from 3.21–3.28 Å. There are a spread of Sm–Ge bond distances ranging from 3.05–3.17 Å. In the third Sm site, Sm is bonded in a 12-coordinate geometry to six Pd and six Ge atoms. There are a spread of Sm–Pd bond distances ranging from 3.01–3.20 Å. There are a spread of Sm–Ge bond distances ranging from 3.12–3.27 Å. There are three inequivalent Pd sites. In the first Pd site, Pd is bonded in a 10-coordinate geometry to six Sm, one Pd, and three Ge atoms. The Pd–Pd bond length is 3.10 Å. There are one shorter (2.58 Å) and two longer (2.60 Å) Pd–Ge bond lengths. In the second Pd site, Pd is bonded in a 10-coordinate geometry to six Sm, one Pd, and three equivalent Ge atoms. There are two shorter (2.59 Å) and one longer (2.64 Å) Pd–Ge bond lengths. In the third Pd site, Pd is bonded in a 10-coordinate geometry to six Sm and four Ge atoms. There are a spread of Pd–Ge bond distances ranging from 2.60–2.94 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to six Sm and four Pd atoms. In the second Ge site, Ge is bonded in a 10-coordinate geometry to six Sm, three equivalent Pd, and one Ge atom. The Ge–Ge bond length is 2.77 Å. In the third Ge site, Ge is bonded in a 10-coordinate geometry to six Sm, three Pd, and one Ge atom.
