The material described by Dy3ReO7 crystallizes in the orthorhombic C222_1 space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Dy site, Dy(2) is bonded to one O(3), one O(4), one O(5), two equivalent O(1), and two equivalent O(2) atoms to form distorted DyO7 pentagonal bipyramids that share corners with two equivalent Re(1)O6 octahedra,  a cornercorner with one Dy(2)O7 pentagonal bipyramid, edges with two equivalent Re(1)O6 octahedra, and edges with three equivalent Dy(2)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles range from 45-48°. Re(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(5) atoms to form ReO6 octahedra that share corners with two equivalent Re(1)O6 octahedra, corners with four equivalent Dy(2)O7 pentagonal bipyramids, and edges with four equivalent Dy(2)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 44°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Dy(1), two equivalent Dy(2), and one Re(1) atom.
