Figure 2
The mol­ecular packing of (I)[link], viewed down the a axis, showing the helical assembly of mol­ecules along the crystallographic twofold screw axis (b axis). Dashed lines indicate inter­molecular C—H⋯O and C—H⋯π inter­actions. H atoms not involved in hydrogen bonding have been omitted for clarity. [Symmetry codes: (i) −x + 2, y + [{1\over 2}], −z + 2; (ii) −x + 2, y − [{1\over 2}], −z + 2.]
