Na 2 (Fe 2/3 Te 4/3 )O 6 ( Z = 3) or Na 3 (FeTe 2 )O 9 ( Z = 2), tris-odium iron(III) ditellurium(VI) nona-oxide, adopts the ilmenite (FeTiO 3 , Z = 6) structure type with the Ti site (site symmetry 3.) replaced by Na and the Fe site (site symmetry 3.) replaced by a mixed-occupied (Fe III ,Te VI ) site in a Fe:Te ratio of 1:2. Whereas the [(Fe,Te)O 6 ] octa-hedron is only slightly distorted, the [NaO 6 ] octa-hedron shows much stronger distortions, as revealed by a larger spread of the bond lengths and some distortion parameters.
