Because of the unique transport properties of charge-transfer (C-T) complexes based on the ..pi..-electron donor molecules, 4,5,4',5'-Bis(alkyldithio)-tetrathiafulvalene, the properties of partially selenium substituted donors bis(alkyldiseleno)-tetrathiafulvalene (BADSe-TTF) were investigated. This paper reports the synthesis of one member of these partially selenium substituted donor molecules, BMDSe-TTF, some structural data for the organometallic compound, (Bu/sub 4/N)/sub 2/(Ni(dsit)/sub 2/), which is the precursor to the BADT-TTF donors, and the pressure dependence of conductivity in the C-T salt, (BMDT-TTF)/sub 2/Au(CN)/sub 2/.
