Abstract

Some new coordination compounds of Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) with butyldithiocarbamate ligand have been synthesised satisfactorily by substitution reaction method in good yield. The characterization of newly synthesized compounds has been performed on the basis of elemental analyses, molar conductance and FT-IR spectroscopy. All the colourless to colourful complexes were inert to atmospheric oxygen and moisture at room temperature. The analytical data indicated the composition ML₂ for the chelates of Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) and M'L₃ for those of Cr(III) and Fe(III). These complexes were observed to be non-ionic in nature. These observations revealed the symmetrical coordination by the bidentate ligand forming four membered ring.

Abstract

The synthesis of sulphur and nitrogen containing dithiocarbamate ligand derived from diisoproylamine as well as its coordination compounds with first series transition metals has been described. These synthesized compounds were characterized through elemental analysis, conductometric measurements and IR spectral studies. The analytical data showed the stoichiometry 1:2 and 1:3 for the compounds of the types ML₂ {M=Mn(II), Co(II), Ni(II), Cu(II) and Zn(II)} and M'L₃{M'=Cr(III) and Fe(III)}, respectively. The conductometric measurements indicated the compounds to be non-ionic in nature. The bidentate nature of dithiocarbamato moiety was confirmed on the basis of IR spectral data.
