PrCe2O6 is Fluorite-derived structured and crystallizes in the orthorhombic Immm space group. Pr(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Ce(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Pr(1) and three equivalent Ce(1) atoms to form OCe3Pr tetrahedra that share corners with six equivalent O(2)Ce2Pr2 tetrahedra, corners with ten equivalent O(1)Ce3Pr tetrahedra, edges with two equivalent O(2)Ce2Pr2 tetrahedra, and edges with four equivalent O(1)Ce3Pr tetrahedra. In the second O site, O(2) is bonded to two equivalent Pr(1) and two equivalent Ce(1) atoms to form OCe2Pr2 tetrahedra that share corners with four equivalent O(2)Ce2Pr2 tetrahedra, corners with twelve equivalent O(1)Ce3Pr tetrahedra, edges with two equivalent O(2)Ce2Pr2 tetrahedra, and edges with four equivalent O(1)Ce3Pr tetrahedra.
PrCe2O6 is Fluorite-derived structured and crystallizes in the orthorhombic Immm space group. Pr(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. All Pr(1)-O(1) bond lengths are 2.47 Å. All Pr(1)-O(2) bond lengths are 2.45 Å. Ce(1) is bonded in a body-centered cubic geometry to two equivalent O(2) and six equivalent O(1) atoms. Both Ce(1)-O(2) bond lengths are 2.37 Å. There are two shorter (2.37 Å) and four longer (2.38 Å) Ce(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Pr(1) and three equivalent Ce(1) atoms to form OCe3Pr tetrahedra that share corners with six equivalent O(2)Ce2Pr2 tetrahedra, corners with ten equivalent O(1)Ce3Pr tetrahedra, edges with two equivalent O(2)Ce2Pr2 tetrahedra, and edges with four equivalent O(1)Ce3Pr tetrahedra. In the second O site, O(2) is bonded to two equivalent Pr(1) and two equivalent Ce(1) atoms to form OCe2Pr2 tetrahedra that share corners with four equivalent O(2)Ce2Pr2 tetrahedra, corners with twelve equivalent O(1)Ce3Pr tetrahedra, edges with two equivalent O(2)Ce2Pr2 tetrahedra, and edges with four equivalent O(1)Ce3Pr tetrahedra.
