SYNTHESIS AND PROPERTIES OF NEW BISDITHIOLENE METAL COMPLEXES OF THE 1,3-DITHIOLE-2-THIONE-4,5-DITHIOLATE (DMIT) LIGAND

Abstract Two series of integer or non-integer oxidation-state metal complexes of the multi-sulfur donor ligand 1,3-dithiole-2-thione-4,5-dithiolate (DMIT) with Cd (II). Hg (II), Sn (II), Mn (II). Fe (II), Co (II). or Bi (III) have been prepared as tetraalkylammonium salts. The compounds are characterized by elemental analysis, 1H NMR spectra, Fourier Transform IR spectra, and UV-Vis spectral analysis. The electrochemical properties of the complexes are also studied by cyclic voltammogram and conductivity measurements on the compressed pellets. A highly conducting LB film is constructed from one of the complexes cetylpyridinium-Cd(dmit)2.
