N, N-(1,2 –Phenylene) dipropionamide was prepared by the reaction of propionyl chloride 6ml, orthophenylene diamine (3g) and triethylamine (6ml) in 100ml of anhydrous toluene. This reaction was refluxed for 16 hours and then allows to stand at room temperature. The temperature was maintained at 110C. Once the temperature of the solvent maintained, the reaction become started. The crude product has been crystallized with ethanol. Brown solid crystals were obtained with 49% yield having melting point 322.71°C. Different metal ligand complexes were prepared with the synthesized ligand. Ligand and complexes were analyzed by using different characterization techniques including X-ray diffraction, FTIR.
