Syntheses and characterization of nano-scale of the MnII complex with 4′-(4-pyridyl)-2,2′:6′,2″-terpyridine (pyterpy): The influence of the nano-structure upon catalytic properties

Nano-scale and single crystals of a new MnII complex, {[Mn(pyterpy)(H2O)(NCS)1.88Cl0.12] · DMF} (1) [pyterpy = 4′-(4-pyridyl)-2,2′:6′,2″-terpyridine] have been synthesized by the reaction of pyterpy and mixtures of manganese(II) acetate and potassium thiocyanate as well as potassium chloride using sonochemical and heat gradient methods, respectively. The nano-structure was characterized by IR spectroscopy and scanning electron microscopy (SEM), and the structure of compound 1 was determined by single-crystal X-ray diffraction. Thermal stability and catalytic properties of nanoparticles and single crystalline samples of compound 1 were studied and are compared with each other.
