Abstract

In this study, transition metal complexes of Mn(II),Co(II) and Ni(II) were synthesized from the aromatic Schiff base ligand derived from 4-aminoantipyrine and p-dimethyl amino benzaldehyde to give the following ligand 4-(4-dimethylamino benzylidene amino)-1,5-dimethyl-2-phenyl-pyrazol-3-one .The structural features were derived from their elemental analyses, melting point, infrared and UV-visible spectroscopy. The FT.IR spectral data suggest the involvement of oxygen of the ring C= O and nitrogen of the azomethine CH = N group in coordination to the central metal ion.
