Synthesis, Characterization, Antimicrobial and Anticorrosion of Studies New 2-(5-(2-(5-hydrazinyl-1,3,4-thiadiazol-2-yl) hydrazinyl)-1,3,4-oxadiazol-2-yl) Phenol With Some Transition Metal Ions

Zainab M. kareem, Hameedi N. Naser.


A new ligand2-(5-(2-(5-hydrazinyl-1,3,4-thiadiazol-2-yl) hydrazinyl)-1,3,4-oxadiazol-2-yl)phenol and its Cu(II) , Co(lll) and Ni(ll) complexes were synthesized . the new ligand and its complexes have been characterization on the basis their spectra of 1HNMR, mass, Fourier transform infrared (FTIR), as well as magnetic susceptibility, atomic absorption, elemental analysis [C, H, N, S] and conductance measurements. The program of Hyperchem 7.51 have been used up for theoretical accounts using PM3 method [1] to study the electrostatic potential that Provided good information about the complexity site. A ligand and its complexes were tested for their antibacterial activity against two kinds of strains Escherichia coli (gram negative bacterial strains) and staphylococcus aureus (gram positivebacteria strains), This research showed excellent results in comparison with Ciprofloxacin as standard drug. The ligand was tested as a corrosion inhibitor for carbon steel in 1 M HCl solution. The corrosion inhibition efficiency was determined by using the weight loss methods

Key words: ligand, complexes, characterization, Hyperchem, electrostatic potential, antibacterial
