The Co(II), Ni(II), Cu(II) and Zn(II) complexes of the composition 1:1:1 molar ratio, (ML1L2) (where L1=diphenylamine-2-mercapto-2-carboxylic acid and L2=2-furyl glyoxalanthranilic acid have been synthesized and characterized by elemental analyses, H-NMR, IR, electronic spectral data and magnetic susceptibility measurements. The synthesized ligands and their metal complexes were screened for their antimicrobial activity against two bacteria Staphylococcus aureus (gram +ve) and Escherichia coli (gram -ve) and two fungi Aspergillus niger and Apergillus flavus by Serial Dilution Method. Metal complexes are more active than their ligands.

The Co(II), Ni(II), Cu(II) and Zn(II) complexes of the composition 1:1:1 molar ratio, (ML1L2) (where L1=diphenylamine-2-mercapto-2-carboxylic acid and L2=2-furyl glyoxalanthranilic acid have been synthesized and characterized by elemental analyses, H-NMR, IR, electronic spectral data and magnetic susceptibility measurements. The synthesized ligands and their metal complexes were screened for their antimicrobial activity against two bacteria Staphylococcus aureus (gram +ve) and Escherichia coli (gram -ve) and two fungi Aspergillus niger and Apergillus flavus by Serial Dilution Method. Metal complexes are more active than their ligands.
