Materials Data on NdFeGe2 by Materials Project
NdFeGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Nd is bonded in a 10-coordinate geometry to five equivalent Fe and ten Ge atoms. There are one shorter (3.36 Å) and four longer (3.37 Å) Nd–Fe bond lengths. There are a spread of Nd–Ge bond distances ranging from 3.20–3.30 Å. Fe is bonded in a 5-coordinate geometry to five equivalent Nd and five Ge atoms. There are one shorter (2.33 Å) and four longer (2.39 Å) Fe–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Nd, one Fe, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.66 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Nd and four equivalent Fe atoms.
