Materials Data on EuGePt by Materials Project

EuPtGe crystallizes in the cubic P2_13 space group. The structure is three-dimensional. Eu is bonded in a 8-coordinate geometry to four equivalent Pt and four equivalent Ge atoms. There are three shorter (3.26 Å) and one longer (3.37 Å) Eu–Pt bond lengths. There are three shorter (3.28 Å) and one longer (3.45 Å) Eu–Ge bond lengths. Pt is bonded in a 3-coordinate geometry to four equivalent Eu and three equivalent Ge atoms. All Pt–Ge bond lengths are 2.42 Å. Ge is bonded in a 3-coordinate geometry to four equivalent Eu and three equivalent Pt atoms.

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.
