Abstract

It has been shown that cesium oxoferrate (VI) decomposes in oxygen at 500 °C giving solid CsxFeIVO2+0.5x (x≈1.0). The oxidation state of iron has been confirmed by Mössbauer spectroscopy data (single symmetrical resonance line with LW=0.4 (1) mm s−1 and isomr shift of 0.15 (2) mm s−1). Cesium oxoferrate (IV), CsxFeO2+0.5x, crystallizes in the face-centered cubic system with the lattice parameter of a=8.36–8.46 Å and has a crystal structure derived from perovskite.
