Metal Complexes as Ligands: Binuclear Alkali Metal and Trinuclear Alkaline Earth Metal Complexes with Nickel (II) and Copper (II) Metal Complexes of isonitrosoacetylacetone
Abstract: In the present study we have synthesized new binuclear complexes of alkali metal salts and trinuclear complexes of alkaline earth metal salts with interaction of stable metal chelates of isonitrosoacetylacetone of Ni (II) & Cu (II) having general formula [Ma (INAA) 2. MbL] and [Ma (INAA) 2. MbX] for alkali metal addcuts [Ma (INAA) 2. MbL2] and [Ma (INAA) 2. MbX2] for alkaline earth metal adducts, where Ma=Ni (II) or Cu (II) and Mb =Li+, Na+, K+ or Mg++, INAA= deprotonated isonitrosoacetylacetone, L=deprotonated 1-nitroso-2-naphthol or 8-hydroxyquinoline and, X= ClO-4 or SCN-. The IR spectral studies suggests that the Ni (II) & Cu (II) metal chelats act as ligand and coordination towards alkali metal salts and alkaline earth metal salts takes place through oxygen atom of bonded ketonic oxygen. The diffuse reflectance electronic spectra and magnetic moment values of the metal chelates and binuclear & trinuclear complexes with alkali metal and alkaline earth metal salts indicates the change in geometry during oxygen bridged complex formation
