The structure described by Fe5Al8 is gamma-brass structured and crystallizes in the cubic I-43m space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 12-coordinate geometry to three equivalent Fe(2), three equivalent Al(1), and six equivalent Al(2) atoms. In the second Fe site, Fe(2) is bonded in a 13-coordinate geometry to one Fe(2), two equivalent Fe(1), two equivalent Al(1), and eight equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 12-coordinate geometry to three equivalent Fe(1), three equivalent Fe(2), three equivalent Al(1), and three equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a 11-coordinate geometry to two equivalent Fe(1), four equivalent Fe(2), one Al(1), and four equivalent Al(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
