摘要： New cobalt(II), copper(II) and zinc(II) complexes of Schiff base derived from D, L-selenomethionine and salicylaldehyde were synthesized and characterized by elemental analysis, IR, electronic spectra, conductance measurements, magnetic measurements and biological activity. The analytical data showed that the Schiff base ligand acts as tridentate towards divalent metal ions (cobalt, copper, zinc) via the azomethine-N, carboxylate oxygen and phenolato oxygen by a stoichiometric reaction of M: L (1 : 1) to form metal complexes [ML(H2O)], where L is the Schiff base ligand derived from D, L-selenomethionine and salicylaldehyde and M = Co(II), Cu(II) and Zn(II). H-1 NMR spectral data of the ligand and Zn(II) complex agree with proposed structures. The conductivity values between 12.87 and 15.63 S cm(2) mol(-1) in DMF imply the presence of non-electrolyte species. Antibacterial and antifungal results indicate that the metal complexes are more active than the ligand. Copyright (C) 2010 John Wiley & Sons, Ltd.
