Abstract

We report the synthesis of a new strontium ruthenium oxycarbonate, Sr₂RuO₄ · 0.25 CO₂, and its use to synthesize Sr₃Ru₂O₇, the n = 2 member of the (SrO)_n+1 (RuO₂)_n Ruddlesden-Popper series. Like layered K₂NiF₄-type Sr₂RuO₄, and three-dimensional perovskite-type SrRuO₃, Sr₃Ru₂O₇ is a metallic conductor. In Sr₃Ru₂O₇, the magnetic moments (d⁴, low spin) interact weakly with each other and develop strong antiferromagnetic correlations below 15 K. Small substitutions of Ir for Ru in Sr₃Ru₂O₇ result in a metal-insulator transition.
