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.
