摘要
Na2(Fe2/3Te4/3)O6（Z = 3）或 Na3(FeTe2)O9（Z = 2），三钠铁(III)二碲(VI)壬氧化物，采用钛铁矿（FeTiO3，Z = 6）结构类型，Ti 位点（位点对称性 3.）被 Na 取代，而 Fe 位点（位点对称性 3.虽然[(Fe,Te)O6]八面体只发生了轻微的畸变，但[NaO6]八面体却表现出了更强烈的畸变，这一点从键长和一些畸变参数的较大分布中可以看出。
Na2(Fe2/3Te4/3)O6 was obtained under hydrothermal conditions and adopts the ilmenite (FeTiO3) structure type.
Na2(Fe2/3Te4/3)O6 (Z = 3) or Na3(FeTe2)O9 (Z = 2), trisodium iron(III) ditellurium(VI) nonaoxide, adopts the ilmenite (FeTiO3, 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 (FeIII,TeVI) site in a Fe:Te ratio of 1:2. Whereas the [(Fe,Te)O6] octahedron is only slightly distorted, the [NaO6] octahedron shows much stronger distortions, as revealed by a larger spread of the bond lengths and some distortion parameters.
