✦ Synopsis

The XRD patterns and the IR and Raman spectra of fine powders of the corundum-type sesquioxides (\alpha-\mathrm{Fe}{2} \mathrm{O}{3}) and (\alpha-\mathrm{Cr}{2} \mathrm{O}{3}), of the ilmenite-type mixed oxides (\mathrm{NiTiO}{3}) and (\mathrm{CoTiO}{3}), and of the mixed oxide (\alpha-\mathrm{FeCrO}{3}) is obtained from the XRD pattern, the IR and Raman spectra provide evidence for the centrosymmetric ilmenitetype superstructure in the case of (\alpha-\mathrm{FeCrO}{3}). The noncentrosymmetric alternative superstructure (\left(\mathrm{LiNbO}_{3}\right.)-like) is excluded by the validity of the mutual exclusion rule. 1994 Academic Press, Inc.

Single crystals of \(\mathrm{NaSbO}_{3}\) with the ilmenite structure have been grown. The crystal structure has been determined by single crystal X-ray diffraction measurement. The ilmenite phase of \(\mathrm{NaSbO}_{3}\) crystallizes in the trigonal system with hexagonal symmetry, space grmip \(R
