Materials Data on NdCoGe3 by Materials Project

Abstract

NdCoGe3 crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Nd is bonded in a 12-coordinate geometry to five equivalent Co and twelve Ge atoms. There are one shorter (3.31 Å) and four longer (3.48 Å) Nd–Co bond lengths. There are a spread of Nd–Ge bond distances ranging from 3.12–3.36 Å. Co is bonded in a 5-coordinate geometry to five equivalent Nd and five Ge atoms. There are one shorter (2.29 Å) and four longer (2.35 Å) Co–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Nd, two equivalent Co, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.79 Å. In the second Ge site, Ge is bonded in a 1-coordinate geometry to four equivalent Nd, one Co, and four equivalent Ge atoms.
