An optimized synthesis of [PPh 4 ][ReO(dmit) 2 ] (dmit 2− = 2‐thioxo‐1,3‐dithiole‐4,5‐dithiolato) is reported as well as electrocrystallization experiments of various donor molecules with this electrolyte. Three 1:1 salts have been obtained with Cp 2 Mo(dmit), BEDT‐TTF [BEDT‐TTF = bis(ethylenedithio)tetrathiafulvalene] and BEDO‐TTF [BEDO‐TTF = bis(ethylenedioxo)tetrathiafulvalene] and their X‐ray crystal structures determined. In the three salts, the closed‐shell, d 2 , [ReO(dmit) 2 ] − anions push apart the radical cations, stabilizing structures with noninteracting donors [with Cp 2 Mo(dmit)] or donor dimers (with BEDT‐TTF or BEDO‐TTF), as confirmed by conductivity and SQUID magnetic susceptibility measurements.
