Materials Data on YbFeGe by Materials Project

Abstract

YbFeGe crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Yb is bonded in a 8-coordinate geometry to six equivalent Fe and five equivalent Ge atoms. There are a spread of Yb–Fe bond distances ranging from 2.89–3.60 Å. There are a spread of Yb–Ge bond distances ranging from 2.98–3.08 Å. Fe is bonded in a 3-coordinate geometry to six equivalent Yb, two equivalent Fe, and three equivalent Ge atoms. Both Fe–Fe bond lengths are 2.49 Å. There are two shorter (2.40 Å) and one longer (2.42 Å) Fe–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to five equivalent Yb, three equivalent Fe, and one Ge atom. The Ge–Ge bond length is 2.73 Å.
