Four Kinds of 21 Helical Assemblies with the Molecular Tilt as Well as Three-directional and Facial Chirality

Abstract

Abstract Four kinds of 21 helical assemblies with a right- or left-handed screw with belly- or back-inside were confirmed in cocrystals of brucine. Discrimination of the different helicities owes to the molecular tilt as well as three-directional and facial chirality of the brucine molecule.
