The structure described by FeNiAl2 is Heusler-like structured and crystallizes in the tetragonal P4/mmm space group. Fe(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Al(1) atoms. Ni(1) is bonded in a body-centered cubic geometry to eight equivalent Al(1) atoms. Al(1) is bonded in a body-centered cubic geometry to four equivalent Fe(1) and four equivalent Ni(1) atoms. is represented by the CIF file [CIF]
