Gd3NTe2O crystallizes in the orthorhombic Pnma space group. There are three inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 4-coordinate geometry to one N(1), two equivalent Te(1), two equivalent Te(2), and three equivalent O(1) atoms. In the second Gd site, Gd(2) is bonded in a 3-coordinate geometry to two equivalent N(1), one Te(2), three equivalent Te(1), and one O(1) atom. In the third Gd site, Gd(3) is bonded in a distorted single-bond geometry to one N(1), two equivalent Te(1), and three equivalent Te(2) atoms. N(1) is bonded to one Gd(1), one Gd(3), and two equivalent Gd(2) atoms to form NGd4 tetrahedra that share  a cornercorner with one O(1)Gd4 tetrahedra, corners with two equivalent N(1)Gd4 tetrahedra, and edges with two equivalent O(1)Gd4 tetrahedra. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 7-coordinate geometry to two equivalent Gd(1), two equivalent Gd(3), and three equivalent Gd(2) atoms. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to one Gd(2), two equivalent Gd(1), and three equivalent Gd(3) atoms. O(1) is bonded to one Gd(2) and three equivalent Gd(1) atoms to form OGd4 tetrahedra that share  a cornercorner with one N(1)Gd4 tetrahedra, corners with two equivalent O(1)Gd4 tetrahedra, edges with two equivalent N(1)Gd4 tetrahedra, and edges with two equivalent O(1)Gd4 tetrahedra.

In the first Gd site, Gd(1) is bonded in a 4-coordinate geometry to one N(1), two equivalent Te(1), two equivalent Te(2), and three equivalent O(1) atoms. The Gd(1)-N(1) bond length is 2.33 Å. Both Gd(1)-Te(1) bond lengths are 3.52 Å. Both Gd(1)-Te(2) bond lengths are 3.50 Å. There is one shorter (2.31 Å) and two longer (2.32 Å) Gd(1)-O(1) bond lengths. In the second Gd site, Gd(2) is bonded in a 3-coordinate geometry to two equivalent N(1), one Te(2), three equivalent Te(1), and one O(1) atom. Both Gd(2)-N(1) bond lengths are 2.33 Å. The Gd(2)-Te(2) bond length is 3.33 Å. There are two shorter (3.43 Å) and one longer (3.59 Å) Gd(2)-Te(1) bond length. The Gd(2)-O(1) bond length is 2.24 Å. In the third Gd site, Gd(3) is bonded in a distorted single-bond geometry to one N(1), two equivalent Te(1), and three equivalent Te(2) atoms. The Gd(3)-N(1) bond length is 2.16 Å. Both Gd(3)-Te(1) bond lengths are 3.10 Å. There are two shorter (3.13 Å) and one longer (3.29 Å) Gd(3)-Te(2) bond length.
