Materials Data on Pr2FeGe4 by Materials Project
Pr2FeGe4 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 11-coordinate geometry to one Fe and ten Ge atoms. The Pr–Fe bond length is 3.27 Å. There are a spread of Pr–Ge bond distances ranging from 3.17–3.32 Å. In the second Pr site, Pr is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Pr–Ge bond distances ranging from 3.16–3.29 Å. Fe is bonded in a 5-coordinate geometry to one Pr and five Ge atoms. There are a spread of Fe–Ge bond distances ranging from 2.32–2.37 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six Pr, one Fe, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.69 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to six Pr and two equivalent Ge atoms. In the third Ge site, Ge is bonded in a 2-coordinate geometry to four Pr and two equivalent Fe atoms. In the fourth Ge site, Ge is bonded in a 2-coordinate geometry to four Pr and two equivalent Fe atoms.
