Palladium complexes of NO type Schiff bases: synthesis, characterization and antioxidant activities

The reaction of o-aminophenol with para hydroxy and methoxy substituted benzaldehydes yielded two Schiff bases. These bases functioning precursors were turned into palladium complexes by treating acetate. structural formulas based on spectral methods (elemental analysis, FT-IR spectroscopy, NMR spectroscopy QTOF-LC/MS spectroscopy) suggested for obtained both complexes. According to the characterization methods, one had also an acetate co-ligand along base ligand. In other complex, central ion was proposed be coordinated Besides, DPPH scavenging activities all synthesized compounds determined compared well-known antioxidant standards. results, mild but lower than parent
