Using the C8H4S82- ligand [2-(4,5-ethylenedithio)-1,3-dithiole-2-ylidiene}-1,3-dithiole-4,5-dithionate(2-)] as an extended pi-electron system, [NBu4n](2) [Pt(C8H4S8)(2)] and Pt(Et2S)(2)(C8H4S8) were prepared. They were oxidized by the ferrocenium, the decamethylferrocenium cation or iodine to form [NBu4n](x)[Pt(C8H4S8)(2)] (x = 0.05-0.4) and Pt(C8H4S8) (Et2S)(0.3)I-1.8, which exhibited electrical conductivities of 1.1-6.9 S cm(-1), measured for compacted pellets at room temperature. The crystal structure of the pro-ligand compound, C8H4S8(CH2CH2CN)(2), revealed a one-dimensional array of dimerized molecules constructed with some sulfur-sulfur non-bonded contacts.
