Structural Chemistry of an n = 1 Member of the Ruddlesden–Popper Srn+1(Co0.5Ta0.5)nO3n+1 Homologous Series: Sr4CoTaO8

A layered perovskite related compound with the Sr4CoTaO8 composition was isolated. This material constitutes the n = 1 member of the recently reported [Srn+1(Co0.5Ta0.5)nO3n+1] Ruddlesden–Popper series. XRPD, SAED and HREM reveal that this compound crystallizes as a K2NiF4-type with space group I4/mmm. The structure is formed by one Sr2CoTaO6 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.
