The known crystal structures of co-ordination compounds containing p-dioxolene ligands in the form of hydroquinone, semiquinone or quinone have been examined. A simple method is proposed to correlate the oxidation state of these ligands with the structural distortion based on crystallographic data. The results fit well with the literature oxidation-state assignments for ligands ligated either to one or to two bridged through the ligand metal ions including the vanadium(IV/V) (hydro/semi)quinonate complexes. © 2007 American Chemical Society.
