Figure 3
Crystal packing of 3 viewed perpendicular to (10) in the region x ≃ 0.75, z ≃ 0.25. For clarity, the following atoms/groups have been omitted: Hydrogen atoms not involved in `weak' hydrogen bonding; two acetyl groups; the bromophenyl groups (except the ipso carbon atom). Dashed lines indicate hydrogen bonds or N⋯S contacts. |
