The crystal structure described by YFe2Al3 crystallizes in the monoclinic C2 space group. Y(1) is bonded in a 11-coordinate geometry to two equivalent Y(1), four equivalent Fe(1), one Al(1), and four equivalent Al(2) atoms. Fe(1) is bonded in a 10-coordinate geometry to two equivalent Y(1), two equivalent Fe(1), two 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 9-coordinate geometry to one Y(1), four equivalent Fe(1), two equivalent Al(1), and two equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a 9-coordinate geometry to two equivalent Y(1), four equivalent Fe(1), one Al(1), and two equivalent Al(2) atoms. is represented by the CIF file [CIF]
