Abstract
In this work, the precursor [2-amino-5-mercapto-1,3,4-thiadiazole][S] has been used in the synthesis of new tridentate ligand [2-(2-Hydroxybenzylidine)amino-5-thiol-1,3,4-thiadiazole][HL] type (N2O). The ligand was refluxed in ethanol with the metal ions [Fe(II), Co(II) and Ni(II)] salts, using KOH as a base in (2:1) molar ratio to give the complexes. These complexes were characterised by atomic absorption(A.A), F.T.I.R, ultraviolet visible(U.V-Vis) spectroscopies, along with conductivity, chroride content and melting point measurement. These studies revealed an octahedral geometries for Fe(II), Co(II) and Ni(II) complexes with the general structure [M(L)2]. The Fe(II) complex exhibited biological activity against the Bacillus(G+) strain, while the other complexes have no biological activity against the two types of bacteria the Bacillus(G+) and the Pseudomonase(G-) strains.
