Synthesis, spectral and thermal study: Transition metal complexes of hydrazone ligand


Author(s): GB Pethe, KA Thakare and AS Aswar

Abstract:
A hydrazone Schiff base ligand 1-(2,5-dihydroxyphenyl)) propylidene) pyrazine-2-carbohydrazideprepared by the condensation of equimolar amounts of 2-5-dihydroxy propiophenone with pyrazine-2-carbohydrazide in ethanol reacts with metal chloride precursor to give complexes of Fe (III), Cr (III),Ti (III), VO (IV), Th (IV), MoO2 (VI) and WO2 (VI) respectively. Structure of ligand was confirmed by elemental analysis, IR, 1H and 13C NMR while complexes were additionally characterized by magnetic susceptibility, molar conductance and thermogravimetric analysis. Spectroscopic studies confirmed a tridentate ONO donor behavior of the ligand towards the central metal ion. The kinetic parameters were evaluated from the thermal decomposition data.
