Gd2Te3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded to two equivalent Te(1), two equivalent Te(3), and three equivalent Te(2) atoms to form a mixture of distorted corner and edge-sharing GdTe7 pentagonal bipyramids. In the second Gd site, Gd(2) is bonded in a 8-coordinate geometry to two equivalent Te(2), three equivalent Te(1), and three equivalent Te(3) atoms. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Gd(1) and three equivalent Gd(2) atoms to form a mixture of distorted corner and edge-sharing TeGd5 trigonal bipyramids. In the second Te site, Te(2) is bonded to two equivalent Gd(2) and three equivalent Gd(1) atoms to form a mixture of corner and edge-sharing TeGd5 square pyramids. In the third Te site, Te(3) is bonded in a 5-coordinate geometry to two equivalent Gd(1) and three equivalent Gd(2) atoms.

In the first Gd site, Gd(1) is bonded to two equivalent Te(1), two equivalent Te(3), and three equivalent Te(2) atoms to form a mixture of distorted corner and edge-sharing GdTe7 pentagonal bipyramids. Both Gd(1)-Te(1) bond lengths are 3.14 Å. There is one shorter (3.14 Å) and one longer (3.22 Å) Gd(1)-Te(3) bond length. There are two shorter (3.13 Å) and one longer (3.17 Å) Gd(1)-Te(2) bond length. In the second Gd site, Gd(2) is bonded in a 8-coordinate geometry to two equivalent Te(2), three equivalent Te(1), and three equivalent Te(3) atoms. Both Gd(2)-Te(2) bond lengths are 3.20 Å. There are two shorter (3.20 Å) and one longer (3.25 Å) Gd(2)-Te(1) bond length. There are two shorter (3.21 Å) and one longer (3.77 Å) Gd(2)-Te(3) bond length. There are three inequivalent Te sites.
