A NEW BINUCLEATING LIGAND, 3-FORMYLSALICYLIC ACID, AND ITS COPPER(II) AND NICKEL(II) COMPLEXES

A new binucleating ligand, 3-formylsalicylic acid, was prepared and its copper(II) and nickel(II) complexes were characterized. On the basis of the analytical, IR, electronic, and magnetic data, it was demonstrated that these complexes have a binuclear structure bridged by the phenolic oxygens. No monomeric complex could be obtained.
