Figure 4
Two zigzag chains of compound 5 parallel to the b axis, centred on the region y ≃ 0.75. The view direction is approximately perpendicular to the bc plane. The molecules are linked via a 2₁ screw axis by a ‘weak' hydrogen bond (Table 2

). Hydrogen atoms not involved in hydrogen bonding are omitted.
