Figure 9
The hydrogen-bonded chain motif (dashed lines) defined by the N—H⋯N≡C interaction in cyanobenzaldehyde iodophenylhydrazone (Ic); see Table 3 for contact geometry. For clarity, only the H atom involved in hydrogen bonding, the N—H atom, is shown; the bridge C—H group is not involved in any hydrogen-bonding motifs.
