Convenient One‐Pot Synthesis of Symmetrical Dithiocarbamates

Abstract Self‐assembled symmetrical metal dithiocarbamates of the type M2(hdtc), where [M = Co(II), Ni(II), Cu(II), Zn(II), Cd(II), and Hg(II) and hdtc = (S2N2C3H4)2CH2] with a closed‐ring system, have been synthesized by a convenient one‐pot synthesis in moderate yields. Based on elemental analyses, IR, TGA, and magnetic susceptibility measurements, a square‐planar geometry has been proposed for the Co(II), Ni(II), and Cu(II) dithiocarbamates, while the Zn(II), Cd(II), and Hg(II) complexes have been suggested to have a tetrahedral geometry. It has been observed that the dithiocarbamato moiety is symmetrically bonded to the metal ion via both sulfur atoms of the –NCS2 group. Since the dithiocarbamates are covalently bonded to the metal ions they are non‐conducting in solution.
