Synthesis and Characterization of Cu (II) Complexes of Dithiocarbamates with Different Substituents

The ligands, disodium diethylenetriamine bis(dithiocarbamate), diendtc and disodium triethylenetetreamine bis(dithiocarbamate), triendtc have been prepared and Cu(II) complexes of of these ligands along with pyrrolidine dithiocarbamate are synthesized. These Cu(II) dithiocomplexes are characterized by elemental analysis, IR, UV, and ESR. The electronic spectra of Cu(II) dithiocomplexes are indicative of square planar(D_2h) symmetry which is supported by ESR spectra of these complexes. The ESR Spectra are also indicative of substantial distortion in Cu(diendtc) and Cu(triendtc) complexes.
