In the frame of our research interest on kojic acid derivatives as powerful chelators for the trivalent iron and aluminium cations [1-4], we have designed, synthesized, and characterized the new ligand 6,6'-(((2-(diethylamino)ethyl)azanediyl)bis(methylene))bis(5-hydroxy-2-(hydroxymethyl)-4H-pyran-4-one), L9. In this communication will be present the study on protonation constants and on the complex formation equilibria with iron and aluminium and with the bivalent essential metal ions, zinc and copper. X-ray structures of the ligand and of some of its metal complexes will be also presented.
