Figure 4
Packing diagram of compound 5, viewed parallel to the c axis in the region z ≃ 3/4. Molecules are connected by classical hydrogen bonds (thick dashed lines) to form ribbons parallel to [110] (horizontal; three such ribbons are shown). Ribbons are connected by weak hydrogen bonds C—H⋯N≡C (thin dashed lines) and perhaps also by C—H⋯π contacts (not drawn explicitly; see text). The alternating orientations of the rings C21–26 and C21′–26′ are clearly recognizable (e.g. at the top of the diagram).. |
