The compound described by NaMnO2 crystallizes in the monoclinic C2/m space group. Na(1) is bonded to six equivalent O(1) atoms to form distorted NaO6 octahedra that share corners with twelve equivalent Mn(1)O6 octahedra, edges with six equivalent Na(1)O6 octahedra, and faces with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 45-50°. Mn(1) is bonded to six equivalent O(1) atoms to form distorted MnO6 octahedra that share corners with twelve equivalent Na(1)O6 octahedra, edges with six equivalent Mn(1)O6 octahedra, and faces with two equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 45-50°. O(1) is bonded in a 6-coordinate geometry to three equivalent Na(1) and three equivalent Mn(1) atoms. is represented by the CIF card [CIF]
