Structure of encapsulated chloride anion with the preorganization of a macrotricyclic ammonium cage host
Abstract
The molecular structure of 2·4Cl–·3H2O, where 2 =[(PhCH2)4N4(C5H10)3(C6H12)3]4+, shows that one chloride anion is encapsulated with the preorganization of its precursor, and held in the intramolecular cavity by the electrostatic potential of four positive units located at the corners of the distorted tetrahedral structure.
