Prevalent geometries of carbohydrate–aromatic CH/π interactions: (A) β-d-glucopyranose can interact via both faces (only the A face is available for α-d-glucopyranose); (B) α- or β-d-galacto- or d-fucopyranose interacts via hydrogens on atoms C3, C4, C5 and C6 (a mirror assembly is typical for l-fucopyranose); (C) β-d-mannopyranose interacts via hydrogen atoms on C1, C2 and C3.
