Figure 5. Supramolecular association in the crystal of 3i: a view of the supramolecular layer parallel to (1 1 0). The N‒H…N hydrogen bonding and N‒H…π(pyrazole) interactions (see ESI Fig. S3 and Table S2†) are shown as orange and blue dashed lines, respectively. Only acidic hydrogen atoms and ipso-carbon atoms of the phenyl groups are shown.
