Synthesis and characterization of schiff-base ligand derivative from 4-aminoantipyrine and its transition metal complexes

الملخص EN

A new ligand 4-[(4-Dimethylamino-benzylidene)-amino]-1, 5-dimethyl-2-phenyl-1,2-dihydro-pyrazol-3-one (L) was synthesized by the reaction of 4-aminoantipyrine with 4-Dimethylamino benzaldehyde in absolute ethanol.

The complexes of Co(II), Zn(II) Cd(II) and Hg(II) with this ligand have been prepared.

The characterization of ligand complexes are verify by elemental analysis, FT-IR, and UV / visible spectra.

Beside, the determination of mole ratio M : L for complexe, determination of metal content M % by flame atomic absorption spectroscopy, molar conductance in absolute ethanol and magnetic moments (μeff.) are presented.
