Materials Data on Eu(GePt)2 by Materials Project

Eu(PtGe)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Eu is bonded in a 12-coordinate geometry to nine Pt and nine Ge atoms. There are a spread of Eu–Pt bond distances ranging from 3.33–3.81 Å. There are a spread of Eu–Ge bond distances ranging from 3.35–3.86 Å. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a 4-coordinate geometry to four equivalent Eu and four equivalent Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.62–2.73 Å. In the second Pt site, Pt is bonded in a 5-coordinate geometry to five equivalent Eu and five Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.66–2.69 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Eu and four equivalent Pt atoms. In the second Ge site, Ge is bonded in a 5-coordinate geometry to five equivalent Eu and five Pt atoms.
