Synthesis, Spectral Characterization and Microbial Activity of Ni (II) Complex with DBAP Schiff’s Base Ligand

Ni (II) complexes were synthetized from the Schiff Base Ligand. The Schiff base ligand [DBAP] (L) is prepared when 3,4- dimethoxy benzaldehyde reacts with 3- amino pyridine. Elemental Analysis, FTIR, UV analysis, HRMS, Magnetic Susceptibility and Molar Conductance data have concluded information regarding the nature of bonding and geometry of the transition metal complex as well as Schiff base Ligand. The Ligand (L) acts as bidentate and co-ordinate through Nitrogen atom of imine group (azomethine group) & Nitrogen atom of the Pyridine ring. Bacterias like E.coli and Bacillus Subtilis (by well disc and fusion method) were used to study the biological activity of the ligand and the Ni(II)complexes. Experimental data revealed that the metal chelates are more active than the free Schiff’s base ligand.
