Pr4CeO10 is Fluorite-derived structured and crystallizes in the tetragonal I4/m space group. Pr(1) is bonded in a body-centered cubic geometry to two equivalent O(1) and six equivalent O(2) atoms. Ce(1) is bonded in a body-centered cubic geometry to eight equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded to three equivalent Pr(1) and one Ce(1) atom to form OCePr3 tetrahedra that share corners with four equivalent O(1)Pr4 tetrahedra, corners with twelve equivalent O(2)CePr3 tetrahedra,  an edgeedge with one O(1)Pr4 tetrahedra, and edges with five equivalent O(2)CePr3 tetrahedra. In the second O site, O(1) is bonded to four equivalent Pr(1) atoms to form OPr4 tetrahedra that share corners with sixteen equivalent O(2)CePr3 tetrahedra, edges with two equivalent O(1)Pr4 tetrahedra, and edges with four equivalent O(2)CePr3 tetrahedra.
Pr4CeO10 is Fluorite-derived structured and crystallizes in the tetragonal I4/m space group. Pr(1) is bonded in a body-centered cubic geometry to two equivalent O(1) and six equivalent O(2) atoms. Both Pr(1)-O(1) bond lengths are 2.46 Å. There are four shorter (2.48 Å) and two longer (2.49 Å) Pr(1)-O(2) bond lengths. Ce(1) is bonded in a body-centered cubic geometry to eight equivalent O(2) atoms. All Ce(1)-O(2) bond lengths are 2.37 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded to three equivalent Pr(1) and one Ce(1) atom to form OCePr3 tetrahedra that share corners with four equivalent O(1)Pr4 tetrahedra, corners with twelve equivalent O(2)CePr3 tetrahedra,  an edgeedge with one O(1)Pr4 tetrahedra, and edges with five equivalent O(2)CePr3 tetrahedra.
