【 摘 要 】

Results of iridium L3edge EXAFS measurements of compounds relevant for water oxidation catalysis are compared to those of other structural techniques. The structural results from EXAFS for the Ir compounds investigated here compare well to those of other structural techniques. Multiple scattering contributions are important in the coordinated Cp∗ and NHC ligands as well as in the IrCl6unit and the IrO2rutile structure. NHC is relatively weak compared to Ir, Cl, and even Cp∗ and O, and often out of phase with the other contributions.
