The arylthio‐substituted tetrathiafulvalenes (Ar‐S‐TTFs) are electron donors having three reversible states, neutral, cation radical, and dication. The charge‐transfer (CT) between Ar‐S‐TTFs ( TTF1 — TTF3 ) and iodine (I 2 ) is reported herein. TTF1 — TTF3 show the CT with I 2 in the CH 2 Cl 2 solution, but they are not completely converted into cation radical state. In CT complexes of TTF1 — TTF3 with I 2 , the charged states of Ar‐S‐TTFs are distinct from those in solution. TTF1 is at cation radical state, and TTF2 — TTF3 are oxidized to dication. The iodine components in complexes show various structures including 1‐D chain of V‐shaped (I 5 ) – , and 2‐D and 3‐D iodine networks composed of I 2 and (I 3 ) – .
