Abstract
Three cyano-bridged 3d–4f bimetallic rectangular tetranuclear compounds, [FeIII(bpy)(CN)2(μ-CN)2]2[LnIII(NO3)2(H2O)3]2·2H2O·2CH3CN (Ln=Y (1), Tb (2), Dy (3); bpy=2,2′-bipyridine), have been prepared by diffusion and characterized by single crystal X-ray diffraction, IR spectra, elemental analysis and magnetic measurement. Single-crystal structural analysis shows that 1–3 are isomorphous and made of a neutral tetranuclear unit [FeIII2LnIII2] with two free water and two acetonitrile molecules. Furthermore, the tetranuclear unit [FeIII2LnIII2] is connected into supermolecular three-dimensional framework through hydrogen bonds. Magnetic susceptibility measurements for compounds 1–3 were performed on polycrystalline samples. For compounds 2 and 3, there is weak ferromagnetic interaction between Fe(III) and Ln(III) ions.
