Abstract:

 

A Schiff base ligand, 2-{(E)-[(6-[(1E)-(2-hydroxyphenyl)  methylene]amino}-pyridin-2-yl)imino]-methyl} phenol (H2PySAL), was  prepared by condensation of 2,6-diaminopyridine and salicylaldehide in  EtOH. The Schiff base ligand was checked by elemental analyses,  1H-NMR, 13C-NMR, IR, UV/Vis, and mass spectral studies.  Three new  mono-, di-, and trinuclear copper(II) complexes of the Schiff base  ligand, formula [Cu(H2PySAL)]Cl2, [Cu2(PySAL) (Phen)]Cl2,  [Cu3(PySAL)2]Cl2, were prepared and characterized by elemental  analyses, magnetic moment, and IR, Uv/Vis, and mass spectral studies.   The spectroscopic data of the complexes indicate that the copper(II)  ions are coordinated by the oxygen atoms and nitrogen atoms (C=N) of  the ligand.  In the dinuclear complex, in which the first Cu(II) ions  were complexed with oxygen and nitrogen atoms of the Schiff base  ligand, the second Cu(II) ions are bridged by dianionic oxygen atoms  of the phenolate groups and are linked to the 1,10-phenanthroline  nitrogen atoms.  The data support the proposed structure of H2PySAL  and its complexes.
