Single crystals of NaSbO3 with the ilmenite structure have been grown. The crystal structure has been determined by single crytal X-ray diffraction measurement. The ilmenite phase of NaSbO3 crystallizes in the trigonal system with hexagonal symmetry, space group R3̄ (No. 148), and Z = 6. The hexagonal unit cell parameters are a = 5.2901(3) Å, c = 15.926(2) Å, and V = 385.98(4) Å3. The structure of ilmenite NaSbO3 is built up from layers of edge-sharing SbO6 octahedra with sodium ions located between the layers in octahedral sites. The ionic conductivity of the ilmenite analog of NaSbO3 was investigated by ac complex impedance measurements and the results are discussed in terms of the structural dimensionality, the Na+-oxygen bond strength, the sodium occupancy, and the bottleneck size.
