The crystal structure of [ClL]2+·2Cl−·3CH3OH, where L = (C6H5CH2)3N4((CH2)6)6, shows the complete encapsulation of a chloride anion into the intramolecular cavity of the macrotricyclic cage L3+. The included anion is held eccentrically into the cavity with a distance of about 4.1 Å from the three charged nitrogen cations and 5.7 Å from the uncharged nitrogen atom.
