Title: Materials Data on ErGe2Pt by Materials Project

Abstract

ErPtGe2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 12-coordinate geometry to six equivalent Pt and eight Ge atoms. There are four shorter (3.20 Å) and two longer (3.33 Å) Er–Pt bond lengths. There are six shorter (3.00 Å) and two longer (3.07 Å) Er–Ge bond lengths. In the second Er site, Er is bonded in a 12-coordinate geometry to four equivalent Pt and ten Ge atoms. All Er–Pt bond lengths are 3.25 Å. There are a spread of Er–Ge bond distances ranging from 3.23–3.46 Å. Pt is bonded in a 10-coordinate geometry to five Er and five Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.49–2.65 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to four Er, three equivalent Pt, and one Ge atom. The Ge–Ge bond length is 2.62 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six Er, two equivalent Pt, and one Ge atom. The Ge–Ge bond length is 2.43 Å.
