Materials Data on HoGe2Pt by Materials Project

Abstract

HoPtGe2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 12-coordinate geometry to four equivalent Pt and ten Ge atoms. All Ho–Pt bond lengths are 3.26 Å. There are a spread of Ho–Ge bond distances ranging from 3.23–3.48 Å. In the second Ho site, Ho is bonded in a 12-coordinate geometry to six equivalent Pt and eight Ge atoms. There are four shorter (3.21 Å) and two longer (3.33 Å) Ho–Pt bond lengths. There are six shorter (3.01 Å) and two longer (3.07 Å) Ho–Ge bond lengths. Pt is bonded in a 10-coordinate geometry to five Ho 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 Ho, three equivalent Pt, and one Ge atom. The Ge–Ge bond length is 2.64 Å. In the second Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Ho, two equivalent Pt, and one Ge atom. The Ge–Ge bond length is 2.41 Å. In the third Ge site, Ge is bonded in a 9-coordinate geometry to six Ho, two equivalent Pt, and one Ge atom. The Ge–Ge bond length is 2.44 Å.
