Materials Data on Nd2Ge2Ir by Materials Project

Abstract

Nd2IrGe2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Nd sites. In the first Nd site, Nd is bonded in a 9-coordinate geometry to three equivalent Ir and six Ge atoms. There are two shorter (3.16 Å) and one longer (3.32 Å) Nd–Ir bond lengths. There are a spread of Nd–Ge bond distances ranging from 2.91–3.51 Å. In the second Nd site, Nd is bonded in a 3-coordinate geometry to one Ir and five equivalent Ge atoms. The Nd–Ir bond length is 2.96 Å. There are a spread of Nd–Ge bond distances ranging from 3.11–3.60 Å. Ir is bonded in a 8-coordinate geometry to four Nd and four Ge atoms. There are a spread of Ir–Ge bond distances ranging from 2.51–2.55 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to eight Nd and two equivalent Ir atoms. In the second Ge site, Ge is bonded in a 6-coordinate geometry to three equivalent Nd, two equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.59 Å.
