The material structure described by FeGe crystallizes in the monoclinic C2/m space group. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 10-coordinate geometry to two equivalent Fe(2), two equivalent Fe(3), two equivalent Ge(1), and four equivalent Ge(2) atoms. In the second Fe site, Fe(2) is bonded in a 10-coordinate geometry to two equivalent Fe(1), two equivalent Fe(3), two equivalent Ge(1), and four equivalent Ge(2) atoms. In the third Fe site, Fe(3) is bonded in a 11-coordinate geometry to one Fe(1), one Fe(2), two equivalent Fe(3), three equivalent Ge(2), and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to one Fe(1), one Fe(2), four equivalent Fe(3), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to two equivalent Fe(1), two equivalent Fe(2), and three equivalent Fe(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
