While n=1,2 phases are typically straightforward to prepare, the synthesis of higher order (n>2) systems is difficult. In this paper we show that chromate (CrO42-) doping can be exploited to stabilise new n=3 Ruddlesden-Popper systems, Sr4Fe3-xCrxO10-δ: without chromate doping, a mixture of the n=2 phase Sr3Fe2O7-x and perovskite-type SrFeO3-x is obtained. This can be explained by the stabilisation of the central perovskite building block by chromate incorporation, similar to prior work on sulfate and carbonate doping in this system. The structure, and Fe/Cr oxidation states were evaluated by X-ray diffraction, 57Fe Mössbauer spectroscopy and X-ray absorption spectroscopy supporting the incorporation of Cr as CrO42-. In order to examine the potential of these new systems for use as a SOFC cathode material, conductivity studies were carried out, which showed semiconducting behaviour with slightly higher conductivities than the sulfate doped counterparts. 2020-02 published University of Birmingham 10.25500/edata.bham.00000442 Dataset research-data@contacts.bham.ac.uk School of Chemistry epsrc other University of Birmingham Spanish Ministry of Science and Innovation yes yes yes TRUE
