A layered perovskite related compound with the Sr 4 CoTaO 8 composition was isolated. This material constitutes the n = 1 member of the recently reported [Sr n +1 (Co 0.5 Ta 0.5 ) n O 3 n +1 ] Ruddlesden–Popper series. XRPD, SAED and HREM reveal that this compound crystallizes as a K 2 NiF 4 ‐type with space group I 4/ mmm . The structure is formed by one Sr 2 CoTaO 6 perovskite block that intergrows with one SrO rock salt layer; no ordering between the Co and Ta cations was established. (© Wiley‐VCH Verlag GmbH & Co.
