Schiff base condensations have long been used to form macrocyclic ligands from diamines and dicarbonyl compounds . Schiff base Complexes have remained an important and popular area of research due to their simple synthesis, versatility and divers range of applications. In this work, macroacyclic ligand (L) has been synthesized from condensation between Naminoethylpipirazine and 2,9-dicarboxaldehyde-1,10-phenanthroline in methanol (Fig.1). In addition, its coordination capability of L toward Cu(ClO4)2.6H2O and NiClO4 have been investigated. The new Ligand and related complexes were characterized by elemental analysis, Mass, IR, and in the case of ligand by 1H and 13C NMR spectroscopy. In the IR spectrum of ligand no peaks attributed to NH2 and carbonyl groups implied that the condensation reaction have been completed.
