The structure described by LuFe4Al8 crystallizes in the tetragonal I4/mmm space group. Lu(1) is bonded in a 20-coordinate geometry to eight equivalent Fe(1), four equivalent Al(1), and eight equivalent Al(2) atoms. Fe(1) is bonded in a 12-coordinate geometry to two equivalent Lu(1), two equivalent Fe(1), four equivalent Al(1), and four equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 10-coordinate geometry to one Lu(1), four equivalent Fe(1), one Al(1), and four equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a 12-coordinate geometry to two equivalent Lu(1), four equivalent Fe(1), two equivalent Al(2), and four equivalent Al(1) atoms. is represented by the CIF card [CIF]
