Özet:

 

A new tetraoxime, (H4L), was prepared in EtOH by reacting  biphenyl-3,3´,4,4´-tetramine with butane-2,3-dione oxime.  The  tetraoxime ligand was characterized by elemental analyses, H-NMR and  13C-NMR, IR, and mass spectral studies.  Dinuclear copper(II),  nickel(II) and tetranuclear copper(II) complexes of tetraoxime ligand  were prepared and characterized by elemental analyses, magnetic  moments, IR, and mass spectral studies.  In the dinuclear metal  complexes, metal:ligand ratio was found as 2:1.  Elemental analyses  and stoichiometric and spectroscopic data of the metal complexes  indicated that the metal ions were coordinated to the nitrogen atoms  of oxime groups (C=N).  In addition, total energy and heat formation  for ligand and dinuclear Cu(II)/Ni(II) complexes by semiempirical PM3  calculations show that square-planar geometry is more stable than  other geometries.
