An air-induced synthesis of a salt [AuCl_2(DDDT)](MET-TTF) (DDDT = 5,6-Dihydro-1,4-dithiin-2,3-dithiolate, MET-TTF = bis(methylthio) ethylenedithiotetrathiafulvalene)

摘要

Reaction of Au(PPh_3)Cl with MET-TTF in the presence of air resulted in a new charge-transfer salt [AuCl_2(DDDT)](MET-TTF) (1, DDDT = 5,6-dihydro-1,4-dithiin-2,3-dithiolate, MET-TTF = bis(methylthio) ethylenedithiotetrathiafulvalene). During the air-induced reaction, the Au(I) is oxidized to Au(III), while two C-S bonds in MET-TTF were cleaved simultaneously. In the crystal the radical cations in 1 are assembled into a 1D structure by intermolecular S ? S, S ?C, and C ?C contacts.
