1,3,4-Oxadiazole derivatives were prepared which have a number of therapeutic applications, and in a purpose of investigating the coordination behavior of new compounds towards transition metal ion, these compounds are prepared by oxidation of 5-aryl-1,3,4-oxadiazole-3-thiol using hydrogen peroxide forming bis(5-aryl-1,3,4-oxadiazole-2-yl) disulfide.The 1,3,4-oxadiazole compounds (L_I, L_II and L_III) have been used as ligands to prepared a number of transition metal complexes, which include [Fe(III), Co(II), Cu(II) and Mn(II)] ions.The ligands were characteriz

         A new schiff base contaning cyclohexyl moiety and phenyl group i.e.

The new ligands have been prepared in this work, which contain  benzothiazole linked to three different aldehydes throw imine group. these three ligands include:

LI=  2- (Acetlidine ) hydrazine benzothiazole.LII= 2- (O -hedroxy benzylidine) hydrazine benzothiazole. LIII=2-(2,4,6- trimethoxy benzylidine) hydrazine benzothiazole.

Which were reacted with the transition metal iones ( Ni(II) , Co(II) , Cu(II) , Cd(II) ).
