Materials Data on Tb(GePt)2 by Materials Project

Abstract

Tb(PtGe)2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Tb is bonded in a 7-coordinate geometry to eight Pt and eight Ge atoms. There are a spread of Tb–Pt bond distances ranging from 3.24–3.40 Å. There are a spread of Tb–Ge bond distances ranging from 3.21–3.36 Å. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a 9-coordinate geometry to four equivalent Tb and five Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.43–2.51 Å. In the second Pt site, Pt is bonded in a 4-coordinate geometry to four equivalent Tb and four equivalent Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.53–2.56 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Tb and five Pt atoms. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Tb and four equivalent Pt atoms.
