Abstract

The possibility of obtaining copper ferrite through the thermal decomposition of the two polynuclear coordination compounds: (NH4)8[Fe2Cu(C2O4)8] (I) and [Fe2Cu(C2O4)2(OH)4]·4H2O (II) was considered. The polynuclear compounds were characterized by various physical chemical techniques, e.g., IR, UV-VIS, EPR, Mössbauer spectra, thermal analysis and magnetic measurements. The final products obtained after thermal decomposition of the complex compounds were analysed by X-ray diffraction. A mixture of tetragonal CuFe2O4, α-Fe2O3 and CuO is generated from the thermolysis of compound I, while a clean tetragonal CuFe2O4 with saturation magnetization of 26.89 emu g−1 is obtained from compound II.
