NITROGEN SULFUR HETEROCYCLIC LIGAND via CLICK CHEMISTRY AND THEIR COMPLEXES WITH Ni(II), Pd(II) AND Pt(IV) SYNTHESIS AND SPECTRAL STUDIES

Abstract

The nitrogen sulfur heterocyclic ligand have been synthesised from two precursors, the first step included the synthesis of the decaalylazide through the reaction between the decayl Iodide and sodium azide, second was prepared by the reaction between the 2,5-dimercapto-1,3,4-thiadiazole with proprgyl bromide, then the two precursors were collected via click chemistry step to obtained the ligand , the complexes were prepared by the addition the salts of metal ions of Ni(II), Pd(II) and Pt(IV) to the ligand solution, three complexes were obtained. The compounds was characterised by FT-IR, UV-Vis, 1H-13C-NMR and Micro elemental analysis C.H.N.S spectroscopies, the molar conductivity and magnetic susceptibility measurements was used for complexes, the solubility of prepared compounds was tested in deferent solvents. From the above studies the suggested geometry is square planar for palladium complex, while the octahedral geometry around the nickel and platinum ions.
