Synthesis, characterization of some transition metal complexes of unsymmetrical tetradentate schiff base and their antimicrobial studies

A new series of Cr(III), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) complexes with tetradentate unsymmetrical Schiff base ligand derived from Dehydroacetic acid, 2-hydroxy benzaldehyde (L) and 6-methyl-1,3,5-triazine-2,4-diamine have been reported. The complexes have been characterized by elemental analysis, magnetic susceptibility measurements, conductrometry, electronic and infrared spectra, X-ray diffraction, 1H-NMR spectra and therogravimetric analysis. The ligand and its complexes were screened for their antibacterial activity against bacterium Staphylococcus aurious, B.subtilis (Gram positive) and Escherichia coli, K.pneumonae (Gram negative). The result indicated that the complexes exhibited good antibacterial activities.
