Abstract:
he work listed by this thesis covers the preparation and characterization ofsome new derivatives of 1,2,4- Triazole as ligands which are : | 1-N : ( 2-ethyl-5-{[(3-phenyl-5-sulfanyl-4H-1,2,4-triazol-4-yl)imino]methyl}benzene-1,4-diol). (L1)2-4-({2-[(4-methylphenyl)amino]ethylidene}amino)-5-phenyl-4H-1,2,4-triazole-3-thiol (L2)3-5-methyl-4-{[1-(5-methylfuran-2-yl)ethylidene]amino}-4H-1,2,4-triazole-3-thiol (L3) | Those ligands were used to prepare some complexes such as L1,L2,L3with the chlorides of transition metal(FeCl3.6H2O,COCl3. 6H2O,CrCl3.6H2O,CuCl2.6H2O,NiCl2.6H2O)To characterize the structure of prepared ligands and their complexes, | elemental analysis (C.H.N),Infrared Spectroscopy (IR), NuclearMagnetic Resonance Spectroscopy(1H-NMR),Mass Spectra,Magneticsensitivity and Molar conductivity techniques were applied . The resultsshowed that ; | 1- The complexes of [Fe(III) , Co(III) , Cr(III)] for all ligands haveshown octahedral configuration. | 2- Complexes of [Ni(II) , Cu(II)] with all ligands have shown square | planer configuration.Testing the biological activity for ligands and their complexes by using spread method and measurement inhibition zone by using (DMSO) as asolvent showed a positivity results; By the appear laeg inhibition zonesagainst E-coli and S. aureas species of bacteria.
