Synthesis, characterization and conducting properties of complex salts and heterobimetallic coordination polymers of the cyanodithioimidocarbonato ligand

The complex salts (NPr4n)2[M′(cdc)2] and the heterobimetallic coordination polymers [MM′(cdc)2] [M = Zn(II), Cd(II), Hg(II), 2Ag(I) or Pb(II); M′ = Ni(II) or Cu(II); cdc2− = cyanodithioimidocarbonate] have been prepared and characterized by elemental analysis, solution and solid state conductivity, magnetic susceptibility, IR, 1H and 13C NMR, UV–Vis, EPR and FAB-mass spectrometry. All of the compounds exhibited semiconducting behaviour.

The reaction of K2[M′(cdc)2]with NPr4nI and metal salts MX2 have afforded complex salts (NPr4n)2[M′(cdc)2] and heterobimetallic coordination polymers [MM′(cdc)2] [M′ = Ni(II) or Cu(II); M = Zn(II), Cd(II), Hg(II), 2Ag(I) or Pb(II)] which have been investigated using spectroscopic, magnetic and solid state electrical concductivity technique.Figure optionsDownload as PowerPoint slide
