Abstract

A new paramagnetic nanocomposite of Pb2MnO4 and PbO was synthesized by thermal decomposition of new metal-organic complex formulated as [Mn(H2O)6][Pb(dipic)2]·2H2O (1) (dipic = pyridine-2,6-dicarboxylic acid). The complex was characterized by atomic absorption, conductivity measurement, elemental analysis, Fourier transform infrared spectroscopy and ultra violet-visible spectroscopy. Thermal behaviour of complex 1 was studied by thermogravimetric analysis and differential scanning calorimetry. The complex 1 used as a precursor for preparation paramagnetic nanoparticles of Pb2MnO4 and PbO by thermal decomposition method at 600 ºC. These nanoparticles were characterized by FT-IR and X-ray diffraction and scanning electron microscopy. The magnetic behaviour of nanoparticles was studied using vibration sample magnetometer at room temperature.
