Figure 4
(a) View in the b direction of the columnar arrangement observed in the crystal structure of (2). (b) View of a column showing the helical arrangement. (c) Between two adjacent columns the hydroxyl groups at C-20 are oriented to each other to yield an O—H⋯O intermolecular contact with an O2—H2⋯O2 angle of 139.6° and an H⋯O2 distance of 3.149 Å resulting, probably, from a electrostatic interaction.
