Two macrocyclic pentaaza compounds containing pyridine evaluated as novel chelating agents in copper(II) and nickel(II) overload

The synthesis and characterization of two pentaaza macrocyclic compounds containing pyridine in the backbone, [15]pyN5 and [16]pyN5, as well as the study of their copper(II) and nickel(II) complexes, are reported in order to evaluate their possible use as chelating agents.
