Figure 4
The packing of (a) compound (1) and (b) compound (2) along the a axis. Displacement ellipsoids are drawn at the 50% probability level. In (2), H atoms are omitted for clarity in compound (1). H atoms involved in hydrogen bonding between chains are drawn as spheres of arbitrary radius, with the other H atoms omitted for clarity. C—H⋯O interactions (Table 2) are shown as dashed lines. |
