Abstract

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.
