Hf2ZrTe crystallizes in the trigonal R3m space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 14-coordinate geometry to four equivalent Hf(2), four equivalent Zr(1), and six equivalent Te(1) atoms. There is one shorter (2.85 Å) and three longer (3.14 Å) Hf(1)-Hf(2) bond lengths. There are three shorter (2.91 Å) and one longer (3.69 Å) Hf(1)-Zr(1) bond length. There are three shorter (3.31 Å) and three longer (3.79 Å) Hf(1)-Te(1) bond lengths. In the second Hf site, Hf(2) is bonded in a 4-coordinate geometry to four equivalent Hf(1) and four equivalent Te(1) atoms. There is one shorter (2.85 Å) and three longer (3.14 Å) Hf(2)-Te(1) bond lengths. Zr(1) is bonded in a 7-coordinate geometry to four equivalent Hf(1) and four equivalent Te(1) atoms. There is one shorter (2.85 Å) and three longer (3.14 Å) Zr(1)-Te(1) bond lengths. Te(1) is bonded in a 11-coordinate geometry to four equivalent Hf(2), six equivalent Hf(1), and four equivalent Zr(1) atoms.
