Ligands that can accommodate two metal ions in close proximity have received considerable attention.Such dinuclear complexes may display unusual properties between metal ions, which are expected to have a synergic effect particularly in the catalytic reactions.In this regard, we have developed a series of dinucleating ligands based on naphthyridine1 and anthyridine2 derivatives (Scheme 1).Dicopper complexes with BPN, BPA and BTPA have been prepared and characterized.
