The coordination behavior of Schiff bases synthesized from phenylenediamine and carbonyl compounds can be justified and introduced in precursor technique in different applications. The investigation and the studies of such Schiff base have preformed because not as coordination chemistry, metal ion uptake or in dyes techniques, but also because their chemistry interest and other applications such as titration analysis, anticorrosion and biological activity. The advantage of salicylaldehyde as a part in the synthesis of the Schiff base and chelate give the chemical compounds very great deal of reactivity, usefulness and as a clear goal of applications. The synthesis and characterization of phenylenediamine Schiff base was performing by different analytical methods. The chemical structures of the Schiff base and its copper chelate have been elucidated by different physiochemical methods such as elemental analysis,molar conductivity, Infrared EPR, NMR and mass spectroscopy. Moreover, all properties may lead to a wild use of such Schiff base.
