NaCeO2 crystallizes in the tetragonal I4_1/amd space group. Na(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. Ce(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles are 15°. O(1) is bonded to two equivalent Na(1) and three equivalent Ce(1) atoms to form a mixture of distorted corner and edge-sharing ONa2Ce3 square pyramids.
NaCeO2 crystallizes in the tetragonal I4_1/amd space group. Na(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. All Na(1)-O(1) bond lengths are 2.42 Å. Ce(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles are 15°. There are two shorter (2.41 Å) and four longer (2.42 Å) Ce(1)-O(1) bond lengths. O(1) is bonded to two equivalent Na(1) and three equivalent Ce(1) atoms to form a mixture of distorted corner and edge-sharing ONa2Ce3 square pyramids.
