NaLaO2 crystallizes in the tetragonal I4_1/amd space group. Na(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. La(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing LaO6 octahedra. The corner-sharing octahedral tilt angles are 18°. O(1) is bonded to two equivalent Na(1) and three equivalent La(1) atoms to form a mixture of corner and edge-sharing ONa2La3 square pyramids.
NaLaO2 crystallizes in the tetragonal I4_1/amd space group. Na(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. All Na(1)-O(1) bond lengths are 2.43 Å. La(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing LaO6 octahedra. The corner-sharing octahedral tilt angles are 18°. There are four shorter (2.43 Å) and two longer (2.47 Å) La(1)-O(1) bond lengths. O(1) is bonded to two equivalent Na(1) and three equivalent La(1) atoms to form a mixture of corner and edge-sharing ONa2La3 square pyramids.
