NaFe(TeO₃)₂

M. Weil and B. Stöger

Abstract: The hydrothermally prepared title compound, sodium iron(III) bis[trioxotellurate(IV)], is isotypic with its Ga^III analogue and consists of corrugated layers with an overall composition of [FeTe₂O₆]^- together with Na⁺ cations. The layers extend parallel to (001) and are made up of [Fe₂O₁₀] edge-shared octahedral dimers and TeO₃ trigonal pyramids sharing vertices. The Na⁺ cations are located in the cavities of this arrangement and link adjacent [FeTe₂O₆]^- layers via distorted [NaO₈] polyhedra.
