    • Although, the geometrical parameter of all three benzenoid rings in the triptycene cation radical are similar (within experimental precision), each ring is crystallographically unique, and therefore, this structure does not suffer from the problem of static crystalline disorder. Furthermore, the X-ray crystallography together with the observation of the intense NIR intervalence transitions in 2 and 3 cation radicals suggests that these intervalence system belongs to Robin Day borderline class II/III systems. Compare: Sun, D.-L.; Lindeman, S. V.; Rathore, R.; Kochi, J. K. J. Chem. Soc., Perkin Trans. 2 2001, 1585.
