The compound described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
