A new azo dye Schiff base ligand, namely N, N′-bis (5-(4-nitrophenyl) diazenyl)-2-hydroxybenzylideneamino)ethylenediimine (NDHBDED) has been synthesized and characterized by analytical techniques. And transition metal complexes of Mn (II), Co (II), Cu (II) and Ni (II) were synthesized by the derived azo dye Schiff base. The complexes were characterized for the elemental analysis, molecular weight determination, electronic spectra, spectral analysis, pH metric method, conductance measurement, magnetic moment measurement at room temperature. Analytical data reveal that Mn (II), Co (II), Cu (II) and Ni (II) complexes posses 1:1 metal-ligand ratios. Schiff base and synthesized complexes were screened for antibacterial and antifungal activities. Co (II) and Cu (II) complexes have been found to be more effective for antimicrobial activity.
