Structural control of ferromagnetic interactions in nickel(II) complexes based on a tetradentate biradical
Abstract
Complexation of a bipyridine-based nitronyl nitroxide biradical with nickel(II) affords two complexes that differ by the nature of one axial ligand and by their magnetic behaviour: in both cases ferromagnetic interactions between high-spin nickel(II) and the radicals are observed.
