Fe2AlTe is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one Fe2AlTe cluster. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 2-coordinate geometry to one Fe(2), one Al(1), and one Te(1) atom. The Fe(1)-Fe(2) bond length is 2.30 Å. The Fe(1)-Al(1) bond length is 0.50 Å. The Fe(1)-Te(1) bond length is 0.60 Å. In the second Fe site, Fe(2) is bonded in a 1-coordinate geometry to one Fe(1) atom. Al(1) is bonded in a 2-coordinate geometry to one Fe(1) and one Te(1) atom. The Al(1)-Te(1) bond length is 0.54 Å. Te(1) is bonded in a 2-coordinate geometry to one Fe(1) and one Al(1) atom.
