Template synthesis of symmetrical transition metal dithiocarbamates
Novel transition metal dithiocarbamates of the type [M2(etdtc)2] and [M¹(etdtc)Cl]2 where M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II), M¹ = Cr(III), Fe(III) and etdtc = (S4N4C11H18 ) have been synthesized by the use of self-assembly techniques. The metal dithiocarbamates we...

| description | Novel transition metal dithiocarbamates of the type [M2(etdtc)2] and [M¹(etdtc)Cl]2 where M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II), M¹ = Cr(III), Fe(III) and etdtc = (S4N4C11H18 ) have been synthesized by the use of self-assembly techniques. The metal dithiocarbamates were prepared from the primary amine, CS2 and metal chloride. They have been characterized by spectroscopic, TGA/DSC, magnetic susceptibility and conductivity data. The complexes, [Mn2(etdtc)2], [Fe2(etdtc)2], [Co2(etdtc)2], [Zn2(etdtc)2], [Cd2(etdtc)2] and [Hg2(etdtc)2] have been suggested to be tetrahedral while [Ni2(etdtc)2] and [Cu2(etdtc)2] have square-planar geometry. [Cr(etdtc)Cl]2 and [Fe(etdtc)Cl]2 have chlorine bridged distorted-octahedral geometry. It has been observed that the dithiocarbamato moiety is symmetrically bonded in all the cases. A three stage TGA profile is observed for all the complexes leading to the formation of respective metal sulfide as the end-product. The molar conductance of 10-3 mol L-1 solution of the complexes measured in DMSO is indicative of their non-ionic nature. |
