The crystal structure described by Fe2Si crystallizes in the tetragonal I4/mmm space group. Fe(1) is bonded in a 8-coordinate geometry to four equivalent Fe(1) and four equivalent Si(1) atoms. Si(1) is bonded in a body-centered cubic geometry to eight equivalent Fe(1) atoms. is represented by the CIF card [CIF]
