Synthesis and characterization and biological study of pyridylazo ligand and its compounds of Co, Ni and Cu divalent ions

Abstract In this work, we synthesized and characterized an azo dye of amino pyridine namely 6-[3- pyridylazo]-2,4-dichlorophenol (PADCP) furthermore its complexes cobalt, nickel copper divalent ions. The infrared spectra refereed that PADCP ligand coordinates by oxygen nitrogen atoms to the metals in as bidentate ligand. have general formula [M(PADCP) 2 ] which confirmed elemental analysis, magnetic moments, molar conductivity electronic spectra. tetrahedral shape non-ionic. exhibit clear color changes under pH changes. shown notable biological activity against E.coli, Staph.aureus Aspergillus Niger
