Abstract: Reactions of disodium salt of the ligands 4,5-dimercapto-1,3-dithiole-thione [H-2(dmit)] and 4,5-dimercapto-1,2-dithiole-3-thione [H-2(dmt)] with ''sodium selenopentathionate''-3-hydrate [Na2Se(S2O3)2].3H2O and ''sodium telluropentathionate''-2-hydrate [Na2Te(S2O3)2.2H2O, in the presence of cations Me3Te+, Ph4As+, (C5H5)2Co+ and PPN+, yielded the corresponding complexes of stoichiometry [cation]2[M(dmit)2] and [cation]2[M(dmt)2]2 (M = Se or Te). These complexes are thermally unstable and undergo redox decomposition in solution. Oxidation reactions of these complexes with iodine or tetracyanoquinodimethane afforded sulphocarbon C6S10. In order to study the oxidation-reduction process of these complexes, detailed electrochemical investigations have been carried out.
