diamines H2N(CH2)nNH2 (n = 2–3) with dicarboxylic acids in the presence of DCC (dicyclohexylcarbodiimide) and DMAP [4-(dimethylamino)pyridine] gave new types of 14–22-membered tetraamide macrocyclic ligands L1L10 which were characterized by element analysis and mass, IR and 1H NMR spectroscopic techniques. The complexes of these macrocyclicmoieties with some transition metal ions have also been synthesized
