摘要
A resolution revolution? Self-assembled chiral structures resulting from the formation of two different helical interactions are found in the crystal structures of the achiral compound 1. The interactions give rise to Ar-H⋯π and OH⋯O=C arrays. The chirality of the helices is spontaneously resolved within individual single crystals. Only one of the hydroxy groups contributes to the formation of a helical hydrogen-bonding array (shown in green).
