El-Tabl, Abdou Saad published the artcileSynthesis, characterization and antimicrobial activity of new binary metal complexes derived from amino sulfo-naphthalene ligand, Recommanded Product: 4-Amino-3-hydroxynaphthalene-1-sulfonic acid, the publication is Journal of Chemical, Biological and Physical Sciences (2015), 5(4), 3629-3644, database is CAplus.
New binary metal (II) complexes derived from amino sulfo-naphthalene ligand were prepared The ligand and the metal complexes were characterized from elemental anal., molar conductance, magnetic susceptibility, IR, electronic, 1H-NMR, and mass spectral studies. Structural and spectroscopic properties revealed that the ligand adopted a tridentate fashion, while the metal complexes adopted a tetragonal distorted octahedral geometry around metal ions. All the complexes are nonelectrolytic in nature as suggested by molar conductance measurements. IR spectral data indicate the coordination between ligand and central metal ion through a phenolic OH, 1-imine N, one oxime-N atoms forming five-membered rings including the metal ions. The compounds were screened for their antimicrobial activities against Aspergillus funigatus, Streptococcs pneumoniae, Bacillis subtilis, Escherichia coli, Pseudomonas coli and candida albicans. Neither the ligand nor its metal complexes recorded antimicrobial activity against neither Pseudomonas coli nor Candida albicans. However, all compounds including the ligand showed high activity against Aspergillus funigatus, Streptococcs pneumoniae, Bacillis subtilis, and Escherichia coli.
