Materials Data on CeFeGe3 by Materials Project

Abstract

CeFeGe3 crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Ce is bonded in a 12-coordinate geometry to five equivalent Fe and twelve Ge atoms. There are one shorter (3.27 Å) and four longer (3.48 Å) Ce–Fe bond lengths. There are a spread of Ce–Ge bond distances ranging from 3.09–3.38 Å. Fe is bonded in a 5-coordinate geometry to five equivalent Ce and five Ge atoms. There are one shorter (2.26 Å) and four longer (2.33 Å) Fe–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 Ce, two equivalent Fe, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.80 Å. In the second Ge site, Ge is bonded in a 1-coordinate geometry to four equivalent Ce, one Fe, and four equivalent Ge atoms.
