Abstract
N-pyridinobenzamide-2-carboxylic acid has been synthesized. Its binary and ternary (using 8-hydroxy-quinoline as the other ligand) Cu(II), Ni(II), Co(II), and Zn(II) complexes have been synthesized and characterized by their elemental analysis, molecular weight determination, molar conductance, infrared and electronic spectral data, and magnetic measurements. Antibacterial activity of these ligands and their metal complexes has been determined on gram-positive (Staphylococcus aureus) and gram-negative (Escherichia coli) bacteria at 37 degrees C, and antifungal activity has been determined on common fungi viz. Aspergillus niger, Aspergillus nidulense, and Candida albicans at 28 degrees C. A considerable increase in the biocidal activity of these ligands on being coordinated with metal ions has been reported.
