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.
