The material structure described by Hf2Te crystallizes in the monoclinic C2/m space group. There are four inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 11-coordinate geometry to two equivalent Hf(1), two equivalent Hf(2), two equivalent Hf(3), three equivalent Hf(4), one Te(1), and one Te(2) atom. In the second Hf site, Hf(2) is bonded to two equivalent Hf(1), two equivalent Te(1), and three equivalent Te(2) atoms to form a mixture of distorted edge and face-sharing HfHf2Te5 trigonal bipyramids. In the third Hf site, Hf(3) is bonded in a 3-coordinate geometry to two equivalent Hf(1), one Te(1), and two equivalent Te(2) atoms. In the fourth Hf site, Hf(4) is bonded in a 2-coordinate geometry to three equivalent Hf(1) and two equivalent Te(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to one Hf(1), one Hf(3), two equivalent Hf(2), and two equivalent Hf(4) atoms. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to one Hf(1), two equivalent Hf(3), and three equivalent Hf(2) atoms. is represented by the CIF file [CIF]
