Abstract

Synthesis and Spectral Studies of some Metal Complexes With N1 N2 bis(2-amino-3,5-dibromo-benzylidene)ethane -1,2-diamine and N1 N4 bis(2-amino-3,5-dibromo benzylidene) butane-1,4-diamine

Microwave assisted synthesis, a green chemistry approach, is now a day’s widely practice in the synthetic laboratories. In the present work two Schiff bases are synthesized using microwave irradiation. Co(II), Cu(II) and Cr(III) complexes of the two new Schiff bases L1= N1, N2-bis(2-amino-3,5-dibromobenzylidene) ethane 1,2- diamine and L2=. N1, N4-bis(2-amino-3,5-dibromobenzylidene)butane-1,4-diamine are synthesized and characterized by microanalysis conductance, HNMR, IR, UV-Visible and mass spectral measurement. The two ligands coordinates through two imine N atoms and two amine N atoms to the metal ions as shown by IR and electronic measurement resulting in six-coordinated Metal ion. The complexes are non electrolyte in the solvent except Cr-complexes are electrolyte (1:1). Studies showed the new Schiff base and their complexes have various activity towards Staphylococcus aurous, Escherichia coli, Bacillus and Pseudomonas.
