摘要：

The preparation of the monostibines o-Me2TTF-SbPh2 (1) and Me3TTF-SbPh2 (2), the ortho distibine o-Me2TTF( SbPh2)(2) (3) and the tetrastibine TTF(SbPh2)(4) (4) is described together with their electrochemical properties and the X-ray crystal structures of the neutral 1 and 3. In the former, one intermolecular Sb...S contact completes the co-ordination sphere of the antimony atom while in 3 the TTF moieties stack on top of each other with no evidence for Sb...S interactions. Electrocrystallisation of 2 in the presence of [n-Bu4N](2) [Mo6O19] affords a 2 : 1 salt, [2](2) [Mo6O19] where the 2(+.) cation radical species are associated into diamagnetic [2](2)(2+) dyads through a strong HOMO ... HOMO overlap interaction, separated from each other by the [Mo6O19](2-) counter ions.
