The compound described by FeSiGe crystallizes in the orthorhombic Cmce space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 8-coordinate geometry to four equivalent Ge(1) and four equivalent Si(1) atoms. In the second Fe site, Fe(2) is bonded in a 8-coordinate geometry to four equivalent Ge(1) and four equivalent Si(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Fe(1), two equivalent Fe(2), two equivalent Ge(1), and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to two equivalent Fe(1), two equivalent Fe(2), three equivalent Ge(1), and two equivalent Si(1) atoms. is represented by the CIF card [CIF]
