Probing Valence Electronic Structures of Fe(III)- and Fe(IV)-Bisamide Complexes Using Fe KBeta XES and 1s3p RIXS

We have synthesized a series of Fe(III)- and Fe(IV)-bisamide complexes to systematically study ligand effects on electronic structures and bonding of the Fe-N4 cores. Herein, we propose to probe the valence electronic structures of these complexes using Fe KBeta x-ray emission (XES) and 1s3p resonant inelastic x-ray scattering (RIXS). Results from these experiments will yield insights that can facilitate our study of reactive intermediates in complex biocatalytic systems, and potentially provide guidance for the development of novel molecular catalysts in the future.
