Pr2Zr2O7 crystallizes in the cubic Fd-3m space group. Pr(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Zr(1) is bonded to six equivalent O(1) atoms to form corner-sharing ZrO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Pr(1) and two equivalent Zr(1) atoms to form distorted OPr2Zr2 tetrahedra that share corners with two equivalent O(2)Pr4 tetrahedra, corners with twelve equivalent O(1)Pr2Zr2 tetrahedra,  an edgeedge with one O(2)Pr4 tetrahedra, and edges with four equivalent O(1)Pr2Zr2 tetrahedra. In the second O site, O(2) is bonded to four equivalent Pr(1) atoms to form OPr4 tetrahedra that share corners with four equivalent O(2)Pr4 tetrahedra, corners with twelve equivalent O(1)Pr2Zr2 tetrahedra, and edges with six equivalent O(1)Pr2Zr2 tetrahedra.
Pr2Zr2O7 crystallizes in the cubic Fd-3m space group. Pr(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Both Pr(1)-O(2) bond lengths are 2.33 Å. All Pr(1)-O(1) bond lengths are 2.61 Å. Zr(1) is bonded to six equivalent O(1) atoms to form corner-sharing ZrO6 octahedra. The corner-sharing octahedral tilt angles are 50°. All Zr(1)-O(1) bond lengths are 2.10 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Pr(1) and two equivalent Zr(1) atoms to form distorted OPr2Zr2 tetrahedra that share corners with two equivalent O(2)Pr4 tetrahedra, corners with twelve equivalent O(1)Pr2Zr2 tetrahedra,  an edgeedge with one O(2)Pr4 tetrahedra, and edges with four equivalent O(1)Pr2Zr2 tetrahedra. In the second O site, O(2) is bonded to four equivalent Pr(1) atoms to form OPr4 tetrahedra that share corners with four equivalent O(2)Pr4 tetrahedra, corners with twelve equivalent O(1)Pr2Zr2 tetrahedra, and edges with six equivalent O(1)Pr2Zr2 tetrahedra.
