Figure 10
The hydrogen-bonded chain motif (dashed lines) defined by the N—H⋯N≡C inter­action in iodo­benzaldehyde cyano­phenyl­hydrazone (IIc)[link]; see Table 5[link] for contact geometry. A corresponding hydrogen-bonded chain motif is observed in the bromo analogue (IIb)[link] (contact geometry given in Table 4[link]). For clarity, only the H atom involved in hydrogen bonding, the N—H atom, is shown; as in (Ic)[link] (Fig. 9[link]), the bridge C—H group is not involved in any hydrogen-bonding motifs. [Symmetry codes: (i) x, −y + [{3\over 2}], z − [{1\over 2}]; (ii) x, −y + [{3\over 2}], z + [{1\over 2}].]
