Dy2TeO6 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 7-coordinate geometry to one O(2), one O(3), one O(4), one O(5), one O(6), and two equivalent O(1) atoms. In the second Dy site, Dy(2) is bonded to one O(2), one O(3), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form distorted DyO7 hexagonal pyramids that share corners with three equivalent Te(1)O6 octahedra, edges with two equivalent Dy(2)O7 hexagonal pyramids, and edges with two equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-45°. Te(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form TeO6 octahedra that share corners with three equivalent Dy(2)O7 hexagonal pyramids and edges with two equivalent Dy(2)O7 hexagonal pyramids. There are six inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Dy(1) and one Te(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Dy(1), one Dy(2), and one Te(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Dy(1), one Dy(2), and one Te(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Dy(1), one Dy(2), and one Te(1) atom. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to one Dy(1), two equivalent Dy(2), and one Te(1) atom. In the sixth O site, O(6) is bonded to one Dy(1), two equivalent Dy(2), and one Te(1) atom to form distorted corner-sharing ODy3Te tetrahedra.
