16. 2O solvent molecule in (S,S)-5 sip had to be refined using the ISOR restraint. The contribution of the hydrogen atoms, in their calculated position, was included in the refinement using a riding model. Upon convergence, the final Fourier difference map showed no significant peaks. CCDC-267206 ((S,S)-5 hip), CCDC-267207 ((S,S)-5 cip), and CCDC-272867 ((S,S)-5 sip) contain the supplementary crystallographic data for this paper.

17. + ion is completed by one contact with the anion, however, outside of its cavity. The ion pair (S,S)-5 sip is denoted as a separated ion pair because of the lack of a direct contact between the potassium ion and the anion although the cryptand penetrates the anion in the solid state.
