  • Abstract

    The solid complexes of Mn(III), VO(IV), MoO2(VI) and UO2(VI) with unsymmetrical dibasic tetradentate ONNO donor Schiff base derived from the condensation of salicylaldenyde, o-hydroxy acetophenone and ethylene diamine have been synthesized and characterized by elemental analysis, magnetic susceptibility measurements, IR and reflectance spectra. The thermal dehydration and decomposition of these complexes were studied kinetically using the Horowitz-Metzger method. The solid state electrical conductivity of complexes has been measured in the temperature range 313 K= T =403 K and the complexes exhibited semiconducting behavior. Scanning electron micrograph has also been reported and suggested homogeneous phase material. Complexes were used for the catalytic oxidation of styrene.
