Anhydrous, anaerobic electrocrystallization techniques have afforded (TSeT)F0.25Cl0.50, the first organic molecular metal to contain off-axis fluoride counterions. This material crystallizes in a unique tetragonal motif with stacks of canted TSeT+0.75 molecules. Disordered chloride and fluoride counterions are found in two different types of channels extending parallel to the stacking axis. Interchain Se...Se interactions are shorter than in the analogous (TSeT+y) (X-)y salts (X- = Cl-, Br-, I-). These structural changes are reflected in the electrical [σ (300K) = 1700 S/cm]; σ (40K) = 7000 S/cm, thermoelectrical, and optical properties of this new organic metal.
