Sythesis, characterization and antibacterial properties of nickel (ii) Schiff base complex derived from benzoin and oamino benzoic acid
The complex of nickel (II) with Schiff base derived from benzoin and o-amino benzoic acid have been prepared and characterized by Infrared spectral analysis, conductance measurement, UVvisible spectral studies and elemental analysis. The melting point of the schiff base determined is 120oC. The decomposition temperature of nickel (II) complex is 155oC, while the molar conductance value is 10.7 ohm-1cm2mol-1. Antimicrobial screening of the compounds were carried out in-vitro against Escherichia coli, Salmonella Typhi (Gram negative) and Staphylococcus aureus, Streptococcus spp. (Gram positive). The bioassay reveals a considerable activity of the Schiff base complex against the bacterial isolates.
