VAlTe2 is Heusler structured and crystallizes in the trigonal R3m space group. V(1) is bonded in a distorted body-centered cubic geometry to four equivalent Te(1) and four equivalent Te(2) atoms. There is one shorter (2.87 Å) and three longer (3.13 Å) V(1)-Te(1) bond lengths. There is one shorter (2.87 Å) and three longer (3.13 Å) V(1)-Te(2) bond lengths. Al(1) is bonded in a 7-coordinate geometry to three equivalent Te(2) and four equivalent Te(1) atoms. All Al(1)-Te(2) bond lengths are 2.92 Å. There is one shorter (2.87 Å) and three longer (3.13 Å) Al(1)-Te(1) bond lengths. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted body-centered cubic geometry to four equivalent V(1) and four equivalent Al(1) atoms. In the second Te site, Te(2) is bonded in a 7-coordinate geometry to four equivalent V(1) and three equivalent Al(1) atoms.
