Preparation and properties of C8H4S8-platinum(II) complexes and electrical conductivities of their oxidized species and X-ray crystal structure of C8H4S8(CH2CH2CN)(2) as a pro-ligand compound

摘要

Using the C8H4S82- ligand [2-{(4,5-ethylenedithio)-1,3-dithiole-2-ylidiene}-1,3-dithiole-4,5-dithion ate(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.
