| Summary: | ABSTRACT<br /> This work includes the synthesis of the ligands (POTL = 5-Phenyl-1,3,4-oxadiazole-2-thiol , NPOTL = 5-(3-Nitro-phenyl)-1,3,4-oxadiazole-2-thiol , and NPOTE = 5-(3-Nitro-phenyl)-3H-1,3,4-oxadiazole-2-thoione . All synthesized ligands were characterized by IR, <sup>1</sup>H-NMR, <sup>13</sup>C-NMR, UV-visible spectra and molar conductivity.<br /> Two nickel(II) complexes of mixed ligands (NPOTE) and en/acac were obtained by the reaction of Ni(OAc)<sub>2</sub>.4H<sub>2</sub>O with (NPOTE), on treatment with ethylenediamine (en) or acetylacetone (acac), gave the complexes of the type [Ni(NPOTE)<sub>2</sub>(en)<sub>2</sub>] , and [Ni(NPOTE)<sub>2</sub>(acac)<sub>2</sub>] respectively. In both complexes, the heterocyclic ligand coordinate through oxadiazole nitrogen, and the ligand exist as a thione form. The characterization data of IR-spectra, UV-visible spectra, conductivity measurement, magnetic susceptibility and atomic absorption, exhibited that both complexes have octahedral geometries around the Ni(II) center. |
