Preparation, Characterization and Antimicrobial Studies of Cu (II) and Mn (II) Complexes with Schiff Base Derived from Benzaldehyde and 2,4-Dinitrophenylhydrazine

Two series of Cu(II) and Mn(II) complexes were prepared by refluxing ethanolic solution of their salts with Schiff base obtained from benzaldehyde and 2,4-dinitrophenylhydrazine into a 1:2 ratio. The prepared compounds were characterized by solubility, molar conductance, and infrared analysis. The complexes show low molar conductance values suggesting non-electrolytic nature. The Schiff ligand and its metal (II) complexes were found to be active against four isolates of bacteria (Salmonella bongori, Streptococcus pyogenes, Staphylococcus aureus and Shingella dysenteriae).
