Packing diagram of compound 5c viewed parallel to the c axis, showing one layer in the region z ≃ 0.25. Dashed lines indicate the hydrogen bonds H01⋯N3 (thick) and four H⋯O (thin). The longer contact H1⋯O10 is also present in this layer, but is omitted for clarity, as are hydrogen atoms not involved in hydrogen bonding. Two atoms are labelled to indicate the asymmetric unit. |
