Synthesis and Characterization of two Closed Side Oxadiazole ligands with their Related Complexes Cu( II ) and Pd(II)

The two oxadiazole new ligands of bis oxadiazol derivatives, have been synthesized by the reaction of 1, 2 - bis - [5=, 2= chloroethylsulphide)]1, 3, 4 - oxadaiazol - 2yl] ethane (l1)and1¯, 2¯ -bis- [5doublebarwedge, 2doublebarwedgechlororthyl sulphi)d],e oxadiazol-2yl] methane (l2.) with adibic acid in presence of ethnolic solution of potassium hydroxide. the mixture was refluxed for eight hours. the ligands were characterized using ir 1h.nmr13c-nmr and mass spectroscopies .the ( l3 ) was used to synthesize complexes with metals cu( ii ) and pd(ii ) . the complexes were studied and identified using ir, uv-vis spectra and molar conductivity, magnetic susceptibility and atomic absorption techniques. the results exhibited that all complexes have an octahedral structure.
