Abstract

A new unsymmetric thioether diamine N - ( 2 - ( 2 - aminophenylthio) ethyl) benzene - 1 , 2 - diamine was prepared through the nucleophilic substitution of cysteaminium chloride with 1 - chloro - 2 - nitrobenzene and then the nitro groups of prepared compuond converted to the amine by zinc powder and ammonium chloride. Then, unsymmetric Schiff bass ligand 2 - ((( 2 - (( 2 - (( 2 - (( 2 - hydroxybenzylidene) amino)phenyl) amino) ethyl) thio) phenyl )imino) methyl )phenol [H2L] was synthesized via [2 + 1] condensation of 2-hydroxybenzaldehyde with this unsymmetric thioether diamine and the corresponding Schiff base complexes of this ligand were prepared by adding metal salts of Zn(II), Cu(II), Ni(II) and Mn(II). The thioether diamine, ligand and unsymmetric Schiff base complexes are characterized by FT - IR, UV - Vis, 1H NMR, 13C NMR spectroscopy, molar conductivity, microanalysis and mass spectrometry
