Summary: | This study provides insights into the electronic structure of an atomically precise Fe/Co
Se
cluster and the extent of redox cooperativity between the Fe active site and the noninnocent Co
Se
support. Chemical oxidation studies enable the isolation of two types of oxidized Fe/Co
Se
clusters, in which the nature of the counterion (I
or OTf
) significantly impacts the structural interactions between Fe and the Co
Se
unit. Experimental characterization by single crystal X-ray diffraction,
Fe Mössbauer spectroscopy, and
P{
H} NMR spectroscopy is complemented by computational analysis. In aggregate, the study reveals that upon oxidation, the charge is shared between the Fe edge site and the Co
Se
core. |
