Reactions And Structural Studies Of Cu(ii) And Fe(iii) Ions With Clofentezine Derivative Of Hydrazine

3,6-Bis(2-hydrazinophenyl)-1,2,4,5-tetrazine has been derivatized from the reaction ofrn3,6-bis (2-chlorophenyl)-1,2,4,5-tetrazine with hydrazine hydrate. Characterization wasrnmade using UV-Vis, IR, IH NMR, and BC NMR spectroscopy. Attempts to preparernmetal complexes between metal ions such as Cu(II), Pe(III), Cr(III) and Ni(II) with thernligand, BHPT, were observed to be the decomposition of BHPT to 3,6-bis (2-rnchlorophenyl)-1,2,4,5-tetrazine. UV-Vis, IR, IH NMR, 13C NMR, AAS, conductivityrnmeasurement and analytical data have been used to characterize BHPT and 3,6-bis (2-rnchlorophenyl)-1,2,4,5-tetrazine.rnThe kinetic study of the decomposition of BHPT to 3,6-bis (2-chlorophenyl)-1,2,4,5-rntetrazine, enhanced by the metal chlorides, revealed that the reaction is a second orderrnwith rate constant of 94.7 morlLsec·1 at 4°C in acetonitrile solution. This reaction wasrnalso tested at pH = 4 (rate constant = 28.06 morILsec·l) and pH = 9.2 (rate constant =rn13.7 morILsec·l) at 50°C. Prom the kinetic data plausible mechanism is proposed.rnAntimicrobial test was conducted for the ligand on Escherichia coli, Proteus andrnStaphilococcus aureus. The ligand has no inhibition effect on the growth of the abovernbacteria
