Abstract

The new perovskite-related layered phase Sr₃Ru₂O₇ has been prepared and characterised: electron microscopy and powder X-ray diffraction shows it to be isostructural with Sr₃Ti₂O₇. This n = 1 structure represents the upper limit of layer thickness for well-ordered material in the homologous series which includes Sr₂RuO₄ and SrRuO₃, the n = 0 and n = ∞ end-members. Preparations between Sr₃Ru₂O₇ and SrRuO₃ are highly disordered, comprising a wide variety of different layer-thicknesses.
