Topochemically Reduced Complex Iridium Oxides

Abstract: In recent years there has been a growing interest in modifying the anion lattice of complex transition metal oxides, via topochemical manipulation, to tune the magnetic and electronic properties of these materials. These processes not only alter the electron count of the phase but also the local symmetry and coordination geometry of the transition metal centres.We have utilized low temperature topochemical anion deintercalation reactions to reduce the ordered double perovskite phase Sr2FeIrO6 to form Sr2FeIrO4, and the n = 1 Ruddlesden-Popper phase and Sr2Fe0.5Ir0.5O4 to form Sr2Fe0.5Ir0.5O3. The two reduced phases are the first observations of Ir2+ centres in an extended oxide phase. We propose to collect neutron powder diffraction data to determine the crystal structures of the two reduced compounds and the nature of the magnetic ordering present at low temperature.
