The crystal structure described by FeGe2 is Khatyrkite structured and crystallizes in the tetragonal I4/mcm space group. Fe(1) is bonded in a 10-coordinate geometry to two equivalent Fe(1) and eight equivalent Ge(1) atoms. Ge(1) is bonded in a 5-coordinate geometry to four equivalent Fe(1) and one Ge(1) atom. is represented by the CIF file [CIF]
