title: Unprecedented redox-driven ligand ejection in nickel(II)-diiminosemiquinonate radical complexes.
abstract: Nickel(II) complexes of (M : L) stoichiometries 1 : 1 (1) and 1 : 2 (2) were prepared from a polydentate ligand involving diiminosemiquinonate radicals. Both were characterized by X-ray diffraction, Vis-NIR and EPR spectroscopy as well as electrochemistry. Ligand-centered oxidation of 1 promotes ligand ejection to give 2.
