Synthesis and characterization of dimeric Schiff base CoII, NiII, CuII complexes for their catalytic application of aerobic oxidation of alcohol and interaction with biomolecules

Three new transition metal (Co(II), Ni(II) and Cu(II)) complexes of Schiff’s base ligand were prepared in situ by refluxing stoichiometric amounts of respective metal salts with 2-hydroxy-1-naphthaldehyde and 2-picolylamine. The structural feature of the synthesized complexes was derived from spectral (FT-IR, UV–Vis and ESI-mass) studies and elemental analysis. The single crystal X-ray diffraction analysis of complex 3 showed the structure as...
