Supramolecular chirality and isomerism in cinchonidine crystals: Hierarchical analysis on the basis of the asymmetric 2(1) helical columnar assembly
We obtained the first cinchonidine inclusion crystal with benzene as a neutral guest. Comparison of the inclusion and guest-free crystal structures by the qualitative hierarchical analysis clarified their supramolecular isomerism of asymmetric 2(1) helical columnar assembly with supramolecular chirality.
