The majority of solid state syntheses utilize high temperature routes restricting the reaction products to the formation of the most thermodynamically stable materials thus precluding the preparation of a large range of metastable phases. We propose to investigate the low temperature anion chemistry of complex metal oxides in order to establish and refine routes to metastable phases with controlled and designed metal-oxygen lattices.Complex manganese oxides are particularly attractive substrates for this study chemically due to the wide range of oxidation states and metal coordinations adopted by manganese in oxide environments. This flexibility allows the full range of low-temperature anion lattice manipulation reactions to be employed (reduction, oxidation and anion exchange) to prepare novel manganese-oxygen connectivities.The diverse range of coupled magnetic and transport phenomena exhibited by complex manganese oxides also makes their investigation attractive. It is proposed that by manipulating the metal-oxygen-metal connectivity in these materials we can control the through anion magnetic super-exchange interactions responsible for this complex behaviour improving our understanding of the systems and ultimately leading to more technologically useful materials.
