Materials Data on Sm2Ge5Pd3 by Materials Project
Sm2Pd3Ge5 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Sm is bonded in a 1-coordinate geometry to seven Pd and ten Ge atoms. There are a spread of Sm–Pd bond distances ranging from 3.21–3.56 Å. There are a spread of Sm–Ge bond distances ranging from 3.08–3.38 Å. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 12-coordinate geometry to four equivalent Sm and six Ge atoms. There are four shorter (2.58 Å) and two longer (2.74 Å) Pd–Ge bond lengths. In the second Pd site, Pd is bonded in a 10-coordinate geometry to five equivalent Sm and five Ge atoms. There are a spread of Pd–Ge bond distances ranging from 2.43–2.56 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Sm, three Pd, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.67 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Sm, three Pd, and two equivalent Ge atoms. In the third Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Sm and four equivalent Pd atoms.
