An organic conductor with a stable metallic state derived from its quasi‐2D Fermi surface is reported. Pyrazinoethylenedithio–TTF is known to form a 2D network which should but does not facilitate conduction through intermolecular N–S and S–S contacts. The exchange of selenium for sulfur in these systems, discussed here, results in the formation of the desired metallic state.
