Materials Data on Pr(FeGe)2 by Materials Project
PrFe2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Pr is bonded in a 8-coordinate geometry to eight equivalent Fe and eight equivalent Ge atoms. All Pr–Fe bond lengths are 3.38 Å. All Pr–Ge bond lengths are 3.16 Å. Fe is bonded to four equivalent Pr and four equivalent Ge atoms to form a mixture of distorted corner, edge, and face-sharing FePr4Ge4 tetrahedra. All Fe–Ge bond lengths are 2.45 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Pr, four equivalent Fe, and one Ge atom. The Ge–Ge bond length is 2.65 Å.
