“…This has been amply demonstrated in cuprate superconductors ((Sr 2 CuO 2 (CO 3 ), 14 (La 1.85 Sr 0.15 Cu 1−x (SO 4 ) x O 4 ) 15 ) or in cobaltites (SrCo 1−x -(SO 4 ) x O 3−y ). 16 Concerning iron compounds, the substitution SrFe 1−x (SiO 4 ) x O 3−y 17 is known for x < 0.15; such a substitution was shown to introduce oxygen vacancy disorder which stabilizes the cubic structure whatever the temperature conditions, making these compounds good candidates for SOFC cathodes. As far as we know, this is the only example of oxyanion substitution in iron perovskite.…”

The new iron layered oxysulfate SrFeO(SO) has been prepared by a solid-state reaction in closed ampules into the form of ceramics and single crystals. Its atomic structure has been solved by means of spectroscopy, diffraction techniques, and high-resolution electron microscopy. SrFeO(SO) is a layered structure that derives from the Ruddelsden-Popper (RP) phases with the layer stacking sequence SrO/SrFeO/SrFe(SO)O/SrFeO. Within the mixed Fe/SO layer, the sulfur atoms are slightly shifted from the B site of the perovskite and each sulfate group shares two corners with iron pyramids in the basal plan without any order phenomenon. The electronic conductivity is thermally activated, while no ionic conductivity is detected.
