Unprecedented Nitronyl Nitroxide Bridged 3d-4f Complexes: Structure and Magnetic Properties
Two novel 2p-3d-4f compounds, {Ln(hfac)(3)[Cu(hfac)(2)](3)(NITPhPyrim)(2)} [Ln = Gd (1), Dy (2)], have been obtained by reacting phenyl pyrimidyl nitronyl nitroxide with Cu(hfac)(2) and Ln(hfac)(3). These two compounds are the first examples of two-dimensional 3d-4f complexes bridged by nitronyl nitroxide radicals. Overall ferromagnetic behaviors were observed in both compounds.
