Pr2Te2O7 crystallizes in the cubic Fd-3m space group. Pr(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Te(1) is bonded to six equivalent O(1) atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 55°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Pr(1) and two equivalent Te(1) atoms to form OPr2Te2 tetrahedra that share corners with two equivalent O(2)Pr4 tetrahedra, corners with twelve equivalent O(1)Pr2Te2 tetrahedra,  an edgeedge with one O(2)Pr4 tetrahedra, and edges with four equivalent O(1)Pr2Te2 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)Pr2Te2 tetrahedra, and edges with six equivalent O(1)Pr2Te2 tetrahedra.
Pr2Te2O7 crystallizes in the cubic Fd-3m space group. Pr(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Both Pr(1)-O(2) bond lengths are 2.39 Å.
