Redox isomerism for quinone complexes of chromium and chromium oxidation state assignment from X-ray absorption spectroscopy
A recent publication presented X-ray absorption data challenging the assignment of charge for members of the [Cr-III(Q)(3)](n), n = 3+ to 3- redox series. Structural, spectral, and magnetic properties reported for various members of the series unambiguously point to ligand-based redox steps with the metal remaining as Cr(III) through the series.
