One-Electron Oxidized Nickel(II)−(Disalicylidene)diamine Complex: Temperature-Dependent Tautomerism between Ni(III)−Phenolate and Ni(II)−Phenoxyl Radical States

Abstract

The one-electron oxidized species of a Ni(II)-phenolate complex has been shown to be in the Ni(II)-phenoxyl radical state at room temperature and the Ni(III)-phenolate state at < -120 degrees C, indicating that the oxidation state is temperature dependent.
