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.
