Abstract: We describe the synthesis and characterization of two new zinc (II) andcadmium (II) complexes of the tetradentate dissymmetric Schiff base ligand 2-((E)-(2-(2-(pyridine-2-yl)ethylthio)ethylimino)methyl)-4-bromophenol (PytBrsalH), prepared from 1-(2-pyridyl)-3-thia-5-aminopentane (pyta) and 5-bromosalicylaldehyde. The complexeswere synthesized by treating an ethanolic solution of the ligand with equimolar amounts ofappropriate metal salts in 1 M methanolic solution of NaOH or alternatively, by a moredirect route in which the two reactants are added to a solution of the ligand immediatelyafter formation of the latter and prior to any isolation. The complexes were characterizedby elemental analysis, FTIR, 1H-NMR, electronic spectra and molar conductivity.According to obtained data, the probable coordination geometries of zinc and cadmium inthese complexes with mixed N, S and O donor atoms are tetrahedral- and octahedral-like,respectively. Both complexes were found to be 1:1 electrolyte systems in acetonitrile.
