Describe the proposed research in about 200 words.Extended arrays of transition metal cations coupled by oxide anions display fundamentally challenging and technologically im cooperative phenomena such as high temperature superconductivity, magnetism and magnetoresistance, ferroelectricity and nanoscale valency ordering and phase separation. In a breakthrough in solid state synthetic chemistry, we have prepared the first transitio: oxide hydride, which supports extended cooperative interactions between the transition metal cations mediated by the hydride The strength of the superexchange coupling and the chemical properties of the oxide hydride both demonstrate strong metal-1 covalency and strongly suggests that the oxide hydride class will display electronic cooperative properties with a range rivaling the oxides. The proposal aims to test the scope of the chemistry and associated physical properties, coupling in-situ difl measurements, designed to understand the unprecedented reduction/insertion reaction affording the oxide hydride, with a synthetic search for other examples, extensive property measurements and DFT band structure calculations to prepare and understand properties of a new family of extended solids. The introduction of metal-hydride covalency to extended transition metal arrays, offer new chemical opportunity to control the properties of highly correlated electronic systems.
