Materials Data on Pr(GePt)2 by Materials Project

Abstract

Pr(PtGe)2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Pr is bonded in a 12-coordinate geometry to eight Pt and eight Ge atoms. There are a spread of Pr–Pt bond distances ranging from 3.30–3.44 Å. There are a spread of Pr–Ge bond distances ranging from 3.27–3.42 Å. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a 9-coordinate geometry to four equivalent Pr and five Ge atoms. There are one shorter (2.48 Å) and four longer (2.53 Å) Pt–Ge bond lengths. In the second Pt site, Pt is bonded in a 4-coordinate geometry to four equivalent Pr and four equivalent Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.56–2.58 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Pr and five Pt atoms. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Pr and four equivalent Pt atoms.
