  4. Abstract:
  5. Four metal dithiocarbamate complexes (Zn, Ni, Hg and Sn) based on an amine containing pyridyl and nitrile groups, 3-((pyridin-2-yl)methylamino)propanenitrile, were prepared and characterized by their elemental analysis, spectroscopic data (such as IR, 1H and 13C NMR), TGA analysis and X-ray crystallography of the Ni(II) complex. The presence of a band in the 1000 cm-1 region in the IR spectra, without any splitting, confirms the symmetrical bidentate bonding mode of the dithiocarbamate ligand. Also, the short thioureide C=N distance in the X-ray analysis of the Ni complex confirms the delocalization of π electrons over the S2CN moiety and strong double bond character between the carbon and nitrogen atoms. In addition, the X-ray analysis reveals that C-Hπ contacts between the -CH2- groups and pyridine ring, and intermolecular C-HN and C-HS hydrogen bonds are effective in the stabilization of the crystal structure and formation of a 3D supra-molecular complex
