The material structure described by Mn2FeGe5 crystallizes in the tetragonal P-4n2 space group. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 6-coordinate geometry to two equivalent Ge(1) and four equivalent Ge(2) atoms. In the second Mn site, Mn(2) is bonded in a 8-coordinate geometry to four equivalent Ge(2) and four equivalent Ge(3) atoms. In the third Mn site, Mn(3) is bonded in a 8-coordinate geometry to two equivalent Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms. Fe(1) is bonded in a 8-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), and four equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 5-coordinate geometry to one Mn(1), two equivalent Mn(3), and two equivalent Fe(1) atoms. In the second Ge site, Ge(2) is bonded in a 4-coordinate geometry to one Mn(1), one Mn(2), two equivalent Mn(3), and one Fe(1) atom. In the third Ge site, Ge(3) is bonded in a 4-coordinate geometry to one Mn(2), one Mn(3), and two equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
