The structure described by FeGe crystallizes in the hexagonal P6/mmm space group. Fe(1) is bonded in a 10-coordinate geometry to four equivalent Fe(1), two equivalent Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a hexagonal planar geometry to six equivalent Fe(1) atoms. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to six equivalent Fe(1) atoms. is represented by the CIF card [CIF]
