Figure 6
A packing diagram viewed down the c axis. Overlapping molecules (projected as `N′ and inverted `N′ letter shapes) indicate the helical chains running along the c axis, which are connected by the intermolecular C—H⋯O interactions (black dashed lines). Only H atoms involved in these interactions are shown for clarity. [Symmetry codes: (ii) −x + 1, y − , −z + ; (iii) −x + 1, y + , −z + .] |
