Abstract :
Six novel monosubstituted dithiocarbamate compounds containing organotellurium(IV) heterocycles, C4H8OTeI[S2CN(CH2CH3)2] (1), C5H10TeI[S2CN(CH2CH3)2] (2), C4H8TeI[S2CN(CH2CH2)2] (3), C8H8TeI[S2CN(CH2CH2)2] (4), C4H8OTeI[S2CN(CH2CH2)2] (5) and C5H10TeI[S2CN(CH2CH2)2] (6) were synthesized. The compounds were characterized by common spectroscopic methods; IR, EI-MS and multinuclear NMR (1H, 13C and 125Te). The structure of compounds 2, 3, 5 and 6 was uniequivocally established by single-crystal X-ray diffraction studies. Compounds 3, 4 and 5 exhibit dimeric arrangements achieved through secondary bonding (Te···S) and in the case of 2, an additional Te···S interaction resulted in the formation of a self-assembled chain. Furthermore, the geometrical arrangement displayed in the tellurium atoms of all the compounds corresponds to a distorted octahedron while the coordination mode for the dithiocarbamate ligands is considered anisobidentate in all cases.
