PrFeGe2 crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 15-coordinate geometry to five equivalent Fe(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. Fe(1) is bonded in a 5-coordinate geometry to five equivalent Pr(1), one Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Fe(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Fe(1) atoms.
PrFeGe2 crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 15-coordinate geometry to five equivalent Fe(1), four equivalent Ge(2), and six equivalent Ge(1) atoms. There are four shorter (3.35 Å) and one longer (3.41 Å) Pr(1)-Fe(1) bond length. There are two shorter (3.19 Å) and two longer (3.24 Å) Pr(1)-Ge(2) bond lengths. There are four shorter (3.22 Å) and two longer (3.31 Å) Pr(1)-Ge(1) bond lengths. Fe(1) is bonded in a 5-coordinate geometry to five equivalent Pr(1), one Ge(1), and four equivalent Ge(2) atoms. The Fe(1)-Ge(1) bond length is 2.32 Å. There are two shorter (2.40 Å) and two longer (2.41 Å) Fe(1)-Ge(2) bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Fe(1), and two equivalent Ge(1) atoms. Both Ge(1)-Ge(1) bond lengths are 2.65 Å. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Fe(1) atoms.
