Figure 2
Crystal packing of 5 viewed parallel to the a axis in the region x ≃ 0.5. Dashed lines indicate classical hydrogen bonds. Naphthyl rings are reduced to the ipso carbon atoms for clarity. Hydrogen atoms not involved in classical hydrogen bonding are omitted. The figure is depth-coded; molecules of the lower layer are drawn with thinner bonds. Atom labels indicate the asymmetric unit (which lies in the lower layer).
