unsymmetrically substituted Ar,H‐edt2− 1,2‐dithiolene ligands (Ar,H‐edt2−=arylethylene‐1,2‐dithiolato; Ar=phenyl (1−), 2‐naphthyl (2−), and 1‐pyrenyl (3−)) were synthesized and characterized by spectroscopic and electrochemical methods and the corresponding neutral species (1, 2, and 3, respectively) were obtained in CH2Cl2 solution at room temperature by diiodine oxidation. The single‐crystal X‐ray
