The compound described by NaNbO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. Na(1) is bonded to six equivalent O(1) atoms to form distorted NaO6 octahedra that share corners with nine equivalent Nb(1)O6 octahedra, edges with three equivalent Na(1)O6 octahedra, and  a faceface with one Nb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-63°. Nb(1) is bonded to six equivalent O(1) atoms to form distorted NbO6 octahedra that share corners with nine equivalent Na(1)O6 octahedra, edges with three equivalent Nb(1)O6 octahedra, and  a faceface with one Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-63°. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Na(1) and two equivalent Nb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
