摘要

Electrooxidation of the nickel dithiolene complex Ni(F_2pdt)_2~(-·) (F_2pdt~(2-): 6,6-difluoro-6,7-dihydro-5H-1,4dithiepine-2,3-dithiolato) affords the corresponding neutral complex Ni(F-2pdt)_2~0 whose layered structure is highly reminiscent, albeit not isostructural, of that of the isosteric fluorinated bis(propylenedithio)tetrathiafulvalene and characterized by a segregation of the fluorinated moieties into fluorous bilayers. The gold neutral complex Au(F_2pdt)_2·, which is isostructural with the fluorinated bis(propylenedithio)tetrathiafulvanene, was prepared by electrocrystallizaiton of the n-Bu_4NAu(F_2pdt)_2 sat. Au(F_2-pdt)_2~· is a semiconductor with high room temperature conductivity. The origin of this semiconducting behavior as well as possible guidelines in order to realize metallic conductivity in gold dithiolene neutral molecular solids are discussed.
