  摘要：

  A series of previously reported mononuclear Cu(II) and homodinuclear Cu(II)Cu(II) complexes, as well as, novel mononuclear Cu(II), homodinuclear Cu(II)Cu(II), and heterodinuclear Cu(II)Ni(II) complexes of a phenol-based dinucleating ligand with two different N(amine)(2)O-2 and N(imine)(2)O-2 coordination sites, were synthesized and characterized by elemental analyses, infrared and electronic absorption spectroscopies and conductivity measurements. The electrochemical behavior and catecholase-like activity of the complexes were also studied using cyclic voltammetry and UV-vis spectrophotometry, respectively. Our results show that the dinuclear complexes are more effective catalysts in the oxidation of catechol to the corresponding quinone than the mononuclear complexes. Furthermore, the homodinuclear Cu(II)Cu(II) complexes show greater catalytic activity compared to the corresponding heterodinuclear Cu(II)Ni(H) complexes. (c) 2005 Elsevier B.V All rights reserved.

  A series of nickel(II) complexes of general formula [Ni2L](ClO4)2 with unsymmetrical compartmental macrocyclic ligands was synthesized by stepwise method using 6,6′-piperazine-1,4-diyldimethylenebis(4-X-2-formylphenol) (X=CH3 or Br), nickel(II) ions and diamines. In this macrocyclic system there are two different N2O2 compartments, one has two piperazinyl nitrogens and two phenolic oxygens and the
