| Abstract | ||
| A new series complexes of the ligand 5-(Benzoxazol-2-ylamino)-1,3,4-thiadiazole-2- thiol (L) have been synthesized by the reaction of the ligand (L) with metals chlorides of Mn(II) , Co(II) , Cu(II) , Zn(II) and Cd(II) in ethanol as a solvent. The ligand 5- (Benzooxazol-2-ylamino)-1,3,4-thiadiazole-2-thiol (L) was prepared from the reaction 5-amino -1,3,4-thiadiazole -2- thiol with 2-Mercaptobenzoxazole in 1,4- dioxane as solvent . The structures of the ligand and its complexes were confirmed by IR , 1H-NMR and UV- Vis. spectra , molar conductivity , melting points elemental analyses(CHN) , atomic absorption and magnetic susceptibility measurements. The synthesized complexes were prepared in (1:2) ratio correspond to Mn(II), Co(II), Cu(II) complexes while in case Zn(II) and Cd(II) complexes is (1:1) ratio (M : L) . These measurements suggested octahedral geometry for the Mn(II) ,Co(II) and Cu(II) complexes and tetrahedral geometry for the Zn(II) and Cd(II) complexes . | ||
