Abstract :
The extremely long C–C bond [1.696(3) Å] in the colorless dispiroacenaphthene-type hexaphenylethane is cleaved readily upon electrochemical transformation into the orange colored naphthalene-1,8-diylbis(acridinium), in which the two cationic units are forced to overlap in a face-to-face manner exhibiting the shortest C+ ⋯ C+ interatomic contact of 2.927(7) Å among the values ever reported.
