Synchrotron light sources provide high flux X-rays for performing local electronic and atomic structure studies around the constituent atoms. In this study, the local structure around TiCl3 catalysts in the complex metal hydride NaAlH4 reveal the gradual transformation from 3+ to 0 oxidation state and corresponding local crystal structures similar to TiAl and TiAl3. Nano-confinement of NaAlH4 into the metalorganic framework, Fe-BTC, reveals that the local atomic structure around open metal site, Fe3+, on the host structure retains its oxidation state but that the local atomic structure is changed by the insertion of the NaAlH4. A structure similar to iron acetate is found in the bare Fe-BTC and the NaAlH4 infiltrated Fe-BTC material.
