| dc.description.abstract | 3,6-Bis(2-hydrazinophenyl)-1,2,4,5-tetrazine has been derivatized from the reaction of 3,6-bis (2-chlorophenyl)-1,2,4,5-tetrazine with hydrazine hydrate. Characterization was made using UV-Vis, IR, IH NMR, and BC NMR spectroscopy. Attempts to prepare metal complexes between metal ions such as Cu(II), Pe(III), Cr(III) and Ni(II) with the ligand, BHPT, were observed to be the decomposition of BHPT to 3,6-bis (2- chlorophenyl)-1,2,4,5-tetrazine. UV-Vis, IR, IH NMR, 13C NMR, AAS, conductivity measurement and analytical data have been used to characterize BHPT and 3,6-bis (2- chlorophenyl)-1,2,4,5-tetrazine. The kinetic study of the decomposition of BHPT to 3,6-bis (2-chlorophenyl)-1,2,4,5- tetrazine, enhanced by the metal chlorides, revealed that the reaction is a second order with rate constant of 94.7 morlLsec·1 at 4°C in acetonitrile solution. This reaction was also tested at pH = 4 (rate constant = 28.06 morILsec·l) and pH = 9.2 (rate constant = 13.7 morILsec·l) at 50°C. Prom the kinetic data plausible mechanism is proposed. Antimicrobial test was conducted for the ligand on Escherichia coli, Proteus and Staphilococcus aureus. The ligand has no inhibition effect on the growth of the above bacteria | en_US |
