Materials Data on La(GePt)2 by Materials Project

Abstract

LaPt2Ge2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La is bonded in a 12-coordinate geometry to eight Pt and eight Ge atoms. There are a spread of La–Pt bond distances ranging from 3.24–3.55 Å. There are a spread of La–Ge bond distances ranging from 3.24–3.60 Å. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a 4-coordinate geometry to four equivalent La and four equivalent Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.52–2.61 Å. In the second Pt site, Pt is bonded in a 5-coordinate geometry to four equivalent La and five Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.52–2.56 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent La and four equivalent Pt atoms. In the second Ge site, Ge is bonded in a 5-coordinate geometry to four equivalent La and five Pt atoms.
