The structure described by Pr2FeGe4 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 11-coordinate geometry to one Fe(1), two equivalent Ge(1), two equivalent Ge(3), two equivalent Ge(4), and four equivalent Ge(2) atoms. In the second Pr site, Pr(2) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(3), two equivalent Ge(4), and four equivalent Ge(1) atoms. Fe(1) is bonded in a 5-coordinate geometry to one Pr(1), one Ge(1), two equivalent Ge(3), and two equivalent Ge(4) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Pr(1), four equivalent Pr(2), one Fe(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to two equivalent Pr(2), four equivalent Pr(1), and two equivalent Ge(1) atoms. In the third Ge site, Ge(3) is bonded in a 6-coordinate geometry to two equivalent Pr(1), two equivalent Pr(2), and two equivalent Fe(1) atoms. In the fourth Ge site, Ge(4) is bonded in a 6-coordinate geometry to two equivalent Pr(1), two equivalent Pr(2), and two equivalent Fe(1) atoms. is represented by the CIF file [CIF]
