Abstract: Dichalcogenene complexes of the formula [cation](n)[M(dmit)(2)](n-), [cation](n)[M(dmt)(2)](n-) and [cation](n)[M(tbs)(2)])(n-) [M = Ni, Cu, Pd, Pt; Au, n = 0-2; dmit = 4,5-dimercapto-1,3-dithiole-2-thione, dmt = 4,5-dimercapto-1,2-dithiole-3-thione and tbs = thiobenezeneselenolate, cation = trimethyltelluronium, (CH3)(3)Te+, bis(triphenylphosphine)iminium, PPN+, tetrabutylammonium, Bu4N+, and trimethylammonium, Me3NH+] have been prepared. The spectroscopic and electrochemical behaviour have been studied and compared with the related complexes. Oxidation reactions of these complexes with iodine afforded partially oxidized derivatives which exhibit compressed electrical conductivites of > 10(-6) S cm(-1) at room temperature. The [PPN][Au(dmit)(2)] complex has been structurally characterized by X-ray crystallography and its structure is compared with the structure of previously reported complexes [(CH3)(3)Te][Au(dmit)(2)] and [PPN][Ni(dmit)(2)].
