Azo dye ligands are a class of basic compounds that are widely used as chromophores, in miscellaneous applications such as dyes, pigments, and noticing materials. Novel change metal aggregates of Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), and Fe(III) incorporating azo chromophore, 3-hydroxy-4-(2,4-dihydroxyphenylazo)naphthalene-1-sulphonic acid (LH) have been combined and characterized. Characterization of combined ligand and complexes were acted from their microanalysis, magnetic susceptibility, bony object in mouth conductance, bulk spectrometry, fluorescence, vibrational, photoelectric, 1H-NMR and ESR spectral studies. Mössbauer spectral study of Fe(II) complexes are stated. The azo ligand coordinates to differing metal entities through O- mite of hydroxy group and N-atom of azo group. The radiance studies reveal improved emission. Cyclic voltametric studies and nonlinear optical (NLO) characteristics were reported for representative aggregates and ligand. The in vitro organic activity of LH and corresponding composites were evaluated against Escherichia coli, Staphylococcus aureus, Aspergillus niger and Candida albicans and the results display that the complexes have potential organic characteristics. Antioxidant activity of the ligand and aggregates was reported utilizing DPPH free radical scavenging technique. The nuclease venture of LH and metal complexes disclose the cleavage of DNA through redox allure.
