- Abstract
Complexes of NiII, CuII, ZnII and CdII metal ions with a novel Schiff base ligand 4-(((3-ethyl-5-mercapto-4H-1,2,4-triazol-4-yl)imino)methyl)-2-methoxy-6-nitrophenol (HTNP) were synthesised, thoroughly characterized by spectral techniques i.e. IR, 1H-NMR, fluorescence, electronic spectra and also structurally examined by elemental analysis, thermal analysis and magnetic moment measurements. A significant enhancement in the fluorescence intensity of HTNP was observed after complexation. Comparative in vitro antimicrobial activities of HTNP and its metal complexes were studied and these novel compounds were found to show moderate to significant antibacterial activity. The results also indicated that antimicrobial activity of the Schiff base ligand (HTNP) gets considerably increased on complexation.
