Abstract: The ligand was synthesized using 3-nitrobenzaldehyde and 1-naphthyl amine in 1:1 ratio. The Cu(II) and V(IV) Schiff base metal complexes were prepared using the synthesized Schiff base ligand in 1:1 ratio. The complexes were characterized using the basic techniques like IR, UV, CHN, molar conductivity and magnetic measurements. The complexes were tested for antibacterial activity against E Coli, Staphylococcus aureus, Kleibsella pneumoniae and Streptococcus mutans and antifungal activity against Aspergillus niger and Candida albicans. The results show that the complexes are potent against some bacteria and fungi at some concentrations.
Key Words: Schiff base, aldehyde, antibacterial, antifungal
I. INTRODUCTION
The recorded beginning of the coordination chemistry is the discovery of hexamine cobalt (III) by Tassert in 1798. With the development of theory of chemical bonding by Pauling, a tremendous change was witnessed in 1940. It enables successful correlation of properties with constitution of co-ordination compounds. Schiff base was formed by the condensation product of a primary amine with a carbonyl compound. Azomethines are reported to have antitumour and cytotoxic activities. Schiff base complexes can be used as catalysts which can catalyse different reactions like decomposition, oxidation, polymerization etc. Schiff base complexes have greater conducting property, resistance towards heat, light and oxidation. The formation of metal complexes were studied by Nunez and Eichhorn.
II. MATERIALS, INSRTUMENTS AND METHODS
2.1 Materials
The chemicals used for the synthesis in the present investigation are of commercial grade and they are directly used without further purification. 3-nitrobenzaldehyde is used as aldehyde and 1-naphthyl amine is used as the amine and the solvent used is methanol.
