Abstract
A new Mn(II) compound, [Mn(pyterpy)(H 2O)(N 3)(NO 3)] ( 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 1 characterized by IR spectroscopy, elemental analyses and X-ray crystallography. The crystal structure of compound 1 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⋯N hydrogen bonds with adjacent molecules. Mn 3O 4 nanoparticles were obtained by thermolyses of compound 1 in oleic acid at 320 °C under air atmosphere. The Mn 3O 4 nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy and thermogravimetric analysis (TGA).
