Synthesis and Characterization of [Benzyl (2-hydroxy-1-naphthylidene) hydrazine carbodithioate] and Its Metal Complexes With [Co(II), Ni(II), Cu(II), Zn(II), and Cd(II)] Ions

The formation of Co(II), Ni(II), Cu(II), Zn(II), and Cd(II)-complexes (C1-C5) respectively wasstudied with new Schiff base ligand [benzyl(2-hydroxy-1-naphthalidene) hydrazine carbodithioatederived from reaction of 2-hydroxy-1-naphthaldehyde and benzyl hydrazine carbodithioate. Thesuggested structures of the ligand and its complexes have been determined by using C.H.N.Sanalyzer, thermal analysis, FT-IR, U.V-Visible, 1HNMR, 13CNMR , conductivity measurement ,magnetic susceptibility and atomic absorption. According to these studies, the ligand coordinatesas a tridentate with metal ions through nitrogen atom of azomethane , oxygen atom of hydroxyl,and sulfur atom of thione and the ratio of ligand to metal (M:L) as (1:2) all the complexes wereoctahedral except copper-complex was distorted octahedral.
