    • The distance between the two ammonium groups of 1.5-pentanediammonium and 1,6-hexanediammonium is estimated to be 7.96 and 8.93 Â, respectively, according to a molecular modeling study (polymer consistent force field, PCFF, in the Material Studio Modeling program).

    • note
    • 2+, presumably due to 1) the much higher solubility of CB[6] in water compared with CB[6] and 2) the flexible cyclohexane rings of CB[6], which seem to hinder an ordered packing of the complexes during crystallization.
