As a result, oxidation chemistry of NiSalens is available only for sterically hindered complexes.

Based on the electrochemical and spectroscopic studies supported by quantum chemical calculations, a rationale for the stability of oxidized nickel complexes with thiophene-based salen ligands was proposed. The introduction of the thiophene core leads to a depletion of spin density on peripheral carbon atoms of the oxidized complex, which switches off its intermolecular reactivity.
