Materials Data on Sm(GePt)2 by Materials Project
Sm(PtGe)2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Sm is bonded in a 7-coordinate geometry to eight Pt and eight Ge atoms. There are a spread of Sm–Pt bond distances ranging from 3.26–3.44 Å. There are a spread of Sm–Ge bond distances ranging from 3.23–3.40 Å. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a 9-coordinate geometry to four equivalent Sm and five Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.45–2.52 Å. In the second Pt site, Pt is bonded in a 4-coordinate geometry to four equivalent Sm and four equivalent Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.53–2.57 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Sm and five Pt atoms. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Sm and four equivalent Pt atoms.
