NaNbO3 crystallizes in the tetragonal P4/mbm space group. Na(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Nb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 0-23°. There are two inequivalent O sites. In the first O site, O(2) is bonded to four equivalent Na(1) and two equivalent Nb(1) atoms to form a mixture of distorted edge and corner-sharing ONa4Nb2 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Na(1) and two equivalent Nb(1) atoms.
NaNbO3 crystallizes in the tetragonal P4/mbm space group. Na(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. All Na(1)-O(1) bond lengths are 2.55 Å. All Na(1)-O(2) bond lengths are 2.79 Å. Nb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles range from 0-23°. Both Nb(1)-O(2) bond lengths are 2.01 Å. All Nb(1)-O(1) bond lengths are 2.01 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded to four equivalent Na(1) and two equivalent Nb(1) atoms to form a mixture of distorted edge and corner-sharing ONa4Nb2 octahedra.
