Synthesis, Structure, and Thermal Properties of Tallium(I) N,N-cyclo-Pentamethylenedithiocarbamate [Tl2{S2CN(CH2)5}2]n: X-Ray Diffraction, 13C and 15N MAS NMR, and Thermal Analysis Studies (An Example of Complicated Structural Organization)

Crystalline polynuclear thallium(I) N,N-cyclo-pentamethylenedithiocarbamate is synthesized by the preparative synthesis. According to the MAS NMR (C-13, N-15) data, its composition includes four structurally nonequivalent dithiocarbamate ligands. According to the X-ray diffraction data, the complex synthesized is a remarkable example for the self-organization of the chemical system with a simple composition into an unusually complicated structure. The latter includes three types of the nonequivalent binuclear molecules [Tl-2{S2CN(CH2)(5)}(2)] (I) performing various structural functions. Two of them (centrosymmetric) alternate and participate in infinite polymeric chain building. The third structural function (noncentrosymmetric) is associated with the joining of the polymeric chains into two-dimensional layers. Structurally nonequivalent binuclear molecules I are shown to be related as conformers. The study of the thermal properties of the complex shows that Tl2S is the final thermal destruction product.
