Dy2Pb2O7 crystallizes in the cubic Fd-3m space group. Dy(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Pb(1) is bonded to six equivalent O(1) atoms to form distorted corner-sharing PbO6 octahedra. The corner-sharing octahedral tilt angles are 58°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Dy(1) and two equivalent Pb(1) atoms to form ODy2Pb2 tetrahedra that share corners with two equivalent O(2)Dy4 tetrahedra, corners with twelve equivalent O(1)Dy2Pb2 tetrahedra,  an edgeedge with one O(2)Dy4 tetrahedra, and edges with four equivalent O(1)Dy2Pb2 tetrahedra. In the second O site, O(2) is bonded to four equivalent Dy(1) atoms to form ODy4 tetrahedra that share corners with four equivalent O(2)Dy4 tetrahedra, corners with twelve equivalent O(1)Dy2Pb2 tetrahedra, and edges with six equivalent O(1)Dy2Pb2 tetrahedra.
