Dy2TeO6 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm space group. Dy(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form DyO6 octahedra that share corners with four equivalent Dy(1)O6 octahedra, corners with four equivalent Te(1)O6 octahedra,  an edgeedge with one Dy(1)O6 octahedra, and  an edgeedge with one Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-61°. Te(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TeO6 octahedra that share corners with eight equivalent Dy(1)O6 octahedra and edges with two equivalent Dy(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-47°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Dy(1) and one Te(1) atom. In the second O site, O(1) is bonded in a trigonal planar geometry to two equivalent Dy(1) and one Te(1) atom.

The corner-sharing octahedral tilt angles range from 44-61°. Both Dy(1)-O(2) bond lengths are 2.29 Å. There are two shorter (2.25 Å) and two longer (2.31 Å) Dy(1)-O(1) bond lengths. Te(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TeO6 octahedra that share corners with eight equivalent Dy(1)O6 octahedra and edges with two equivalent Dy(1)O6 octahedra.
