| Abstract A dibasic tetradentate Schiff base ligand; 2,5-bis(o-hydroxyphenylimino)hexane, (H2L), and their new binuclear complexes have been synthesized and characterized on the basis of analytical, spectral, magnetic and conductance measurements. The compositions of these complexes were found to be [(M)2(L)2(H2O)4] (where M = Co(II) or Cu(II)) ; [(Zn)2(L)2].2H2O ; and [(Ni)2(L)2].14H2O (in molar ratio of 2:2 as metal : ligand) ; also [(M)2(L)(Cl)2)(H¬2O)2] (where M =Co(II), Ni(II), Cu(II) or Zn(II) (in molar ratio of 2:1 as metal : ligand). The overall IR data suggest the dibasic, tetradentate (N2O2) nature of the ligand. The decomposition degrees and insolubility in common organic solvents support the binuclear structure of these complexes. Conductance measurements show a non electrolytic nature of the complexes. | ||
