The polynuclear complexes of iron(II,III) and copper(II) with cyanide as bridging ligand

Article abstract of DOI:10.1080/00945719608005145

Five novel complexes of the type [CuL₂][Fe(CN)₅NO]. xH₂O (L = ethylenediamine (en), x = 0; L = o-phenanthroline (phen) or 2,2′-bipyridine (bpy), x = 2), [CuL₂]₃[Fe(CN)₆]₂. xH₂O (L = bpy, x = 6; L = phen, x = 9) have been prepared and studied by elemental analyses, thermal analyses, IR and UV - vis. spectra and magnetic measurements. The structures are proposed with cyanide bridges between Fe(II) and Cu(II) (nitroprusside complexes) or between Fe(III) and Cu(II) (hexacyanoferrate(III) complexes). The temperature dependence of the magnetic susceptibility of the complex [Cu(bpy)₂]₃[Fe(CN)₆]₂. 6H₂O was measured in the range 94.4 - 293.5 K but no exchange interaction was found. The product of the thermal decomposition of the complex [Cu(bpy)₂]₃[Fe(CN)₆]₂.6H ₂O is a mixture of CuO and CuFe₂O₄, as determined by X-ray powder diffraction.
