Materials Data on YFeGe2 by Materials Project

Abstract

YFeGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Y is bonded in a 10-coordinate geometry to five equivalent Fe and ten Ge atoms. There are four shorter (3.29 Å) and one longer (3.37 Å) Y–Fe bond lengths. There are a spread of Y–Ge bond distances ranging from 3.13–3.21 Å. Fe is bonded in a 5-coordinate geometry to five equivalent Y and five Ge atoms. There are a spread of Fe–Ge bond distances ranging from 2.29–2.38 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Y, one Fe, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.60 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Y and four equivalent Fe atoms.
