Synthesis and characterization of Mn3O4 nanoparticles via thermal decomposition of a new synthesized hydrogen bonded polymer
摘要:
A new Mn(II) compound, [Mn(pyterpy)(H2O)(N-3)(NO3)] (1) [pyterpy = 4'-(4-pyridyl)-2,2',6',2 ''-terpyridine], was synthesized by the reaction of pyterpy and mixtures of manganese(II) nitrate and sodium azide using heat gradient method. The compound I characterized by IR spectroscopy, elemental analyses and X-ray crystallography. The crystal structure of compound I was determined by single-crystal X-ray diffraction. The potentially tetradentate pyterpy ligand acts as a tridentate donor. The noncoordinated pyridyl group interacts via O-H center dot center dot N hydrogen bonds with adjacent Molecules. Mn3O4 nanoparticles were obtained by thermalyses of compound I in oleic acid at 320 degrees C under air atmosphere. The Mn3O4 nanoparticles were characterized by X-ray diffraction (XRD). scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy and thermogravimetric analysis (TGA).
