Na2PrO3 crystallizes in the tetragonal P4/mmm space group. Na(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Pr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing PrO6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Na(1) and two equivalent Pr(1) atoms to form corner-sharing ONa4Pr2 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded in a square co-planar geometry to two equivalent Na(1) and two equivalent Pr(1) atoms.
Na2PrO3 crystallizes in the tetragonal P4/mmm space group. Na(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Na(1)-O(1) bond lengths are 2.39 Å. Both Na(1)-O(2) bond lengths are 2.40 Å. Pr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing PrO6 octahedra. The corner-sharing octahedra are not tilted. Both Pr(1)-O(1) bond lengths are 2.40 Å. All Pr(1)-O(2) bond lengths are 2.39 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Na(1) and two equivalent Pr(1) atoms to form corner-sharing ONa4Pr2 octahedra. The corner-sharing octahedra are not tilted.
