Materials Data on PrFeGe2 by Materials Project

Abstract

PrFeGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Pr is bonded in a 10-coordinate geometry to five equivalent Fe and ten Ge atoms. There are four shorter (3.35 Å) and one longer (3.41 Å) Pr–Fe bond lengths. There are a spread of Pr–Ge bond distances ranging from 3.19–3.31 Å. Fe is bonded in a 5-coordinate geometry to five equivalent Pr and five Ge atoms. There are a spread of Fe–Ge bond distances ranging from 2.32–2.41 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Pr, one Fe, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.65 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Pr and four equivalent Fe atoms.
