المستخلص:
Synthesis of Schiff base during the condensation of salicylaldehyde with substituted aniline in ethanolic acid medium using glacial acidic acid are reported . Metal complexes of ( Cu , Ni , Co ) as hydrated acetate salts ,the dehydration of salts was carried out by drying the hydrate salts in oven for several hours at 100 - 110 C . Several spectral techniques such as UV - Visible , FTIR and CHN analysis were used to identify the chemical structures of the reported ligands and there complexes . Mole ratio and continuous variation showed that the (M : L) ( 1 : 2 ) ratio for all metal - complex . The antibacterial was investigated against two pathogenic bacteria namely Aeromomas hydrophila ( - ) , Staphylococcus aureus (+) the result showed that both ligands and complexes are biologically active .Thermo gravimetric analysis ( TG ) for all complexes were also evaluated their thermal degradation studies using TG analytical methods , thermodynamic parameters ( ΔS , ΔH , ΔG ) were evaluated from TG curve using Vant Hoff method
