EXAFS copper complexes

With the exception of Elder et. al., who used EXAFS to look at redox properties of copper complexes diffused in Nafion film modified electrodes (21), no in-situ studies have been reported on modified electrodes using EXAFS. 

Stack and co-woikers [25] have synthesized model complexes that resemble both the spectroscopic characteristics and the catalytic activity of galactose oxidase. For these complexes, EXAFS and edge XAS experiments indicate that the radical is most likely located axially in the non-square planar coordination of the copper. Calculations by Rothlisberger and Carloni [26] on these model systems confirm this fact. We also recommend the chapter herein by that group, in which the fuU reaction mechanism of GO has been investigated using Car-ParineUo MD methods. 

Rh2(At-02CC H2 i)4] for n = 4-24 behave very similarly to the copper complexes and form, on heating, columnar meso-phases. Rh-K-edge EXAFS measurements showed no change in the core structure passing from the solid state to the mesophase [48].
