New Complexes with Triazole Schiff Bases Derivative Ligand Containing Aspirin: Synthesis, Structure, Conductivity and Magnetic Susceptibility

ABSTRACT---Complexes of Cu(II) ), Ni (II) and Co (II) of a new triazole Schiff-base of two different ligand ,namely(E)-2-(4-((2-hydroxybenzylidene)amino)4H1,2,4-triazol-3-yl)phenyl acetate and (E)-2-(4-((2-hydroxy-4methoxybenzylidene)amino)-4H-1,2,4-triazol-3-yl)phenyl acetate were prepared and characterized by elemental analysis, H, C-NMR, FTIR and UV-Visible spectroscopic data. The complex is found to be an ionic in nature by conductivity measurements and have been found to posses 1:2(M:2L) stoichiometry. The magnetic moment values of 1.540–1.7295.B.M. for Cu(II) complexes without doubt recommend octahedral geometry with one unpaired electron for Cu(II) complexes. The magnetic moment values of 3.863–4.039 B.M. for Co(II) complexes that recommend high spin octahedral geometry with three unpaired electron for Co(II) complexes. The magnetic moment value of 2.351B.M. for Ni(II) complex was matches to two unpaired electrons and octahedral geometry. Considerable variations in biological activity with structure and types are observed for these complexes.
