Figure 11
The mol­ecular packing in (III)[link], showing the R22(8) hydrogen-bonding inter­action (dashed lines) between the nitro group and the bridge N—H and C—H groups. For clarity, only the H atoms of the bridge are shown. See Table 6[link] for contact geometries. [Symmetry codes: (i) x − 1, y + 1, z; (ii) x, y − 1, z; (iii) x + [{1\over 2}], −y + 1, z + [{1\over 2}]; (iv) x − [{1\over 2}], −y + 2, z + [{1\over 2}].]
