characterization of chemical and electrochemical synthesis of some metal chelates derived from ethyl benzoylacetate hydrazide

ABSTRACT

Coordination compounds of some transition metal ions with the hydrazide derivative of ethyl benzoyl acetate were synthesized by both chemical and electrochemical techniques. Their structures were elucidated by elemental analysis, molar conductance, magnetic susceptibility [at 25 degree] and spectral [IR, UV-vis, esr] studies. The IR spectra showed that the ligand reacted mostly in the enol form except for the complex derived from hydrated Cu [II] sulfate. The thermal stability of the complexes was investigated by differential thermal analysis [DTA]
