The crystal structure described by NaTmO2 crystallizes in the tetragonal I4_1/amd space group. Na(1) is bonded to six equivalent O(1) atoms to form distorted NaO6 octahedra that share corners with two equivalent Tm(1)O6 octahedra, corners with four equivalent Na(1)O6 octahedra, edges with four equivalent Na(1)O6 octahedra, and edges with eight equivalent Tm(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-13°. Tm(1) is bonded to six equivalent O(1) atoms to form TmO6 octahedra that share corners with two equivalent Na(1)O6 octahedra, corners with four equivalent Tm(1)O6 octahedra, edges with four equivalent Tm(1)O6 octahedra, and edges with eight equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-13°. O(1) is bonded to three equivalent Na(1) and three equivalent Tm(1) atoms to form a mixture of distorted edge and corner-sharing ONa3Tm3 octahedra. The corner-sharing octahedral tilt angles range from 0-13°. is represented by the CIF file [CIF]
