The material described by NaNbO2 is H-Phase structured and crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded to six equivalent O(1) atoms to form NaO6 octahedra that share corners with six equivalent Nb(1)O6 pentagonal pyramids, edges with six equivalent Na(1)O6 octahedra, and edges with six equivalent Nb(1)O6 pentagonal pyramids. Nb(1) is bonded to six equivalent O(1) atoms to form distorted NbO6 pentagonal pyramids that share corners with six equivalent Na(1)O6 octahedra, edges with six equivalent Na(1)O6 octahedra, and edges with six equivalent Nb(1)O6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 5°. O(1) is bonded to three equivalent Na(1) and three equivalent Nb(1) atoms to form a mixture of corner, face, and edge-sharing ONa3Nb3 octahedra. The corner-sharing octahedral tilt angles range from 0-47°. is represented by the Crystallographic Information File (CIF) [CIF]
