The two crystal structures of enamines derived from 1-n-alkyl-3-methylpyrazol-5-ones such as C19H27N 3O and C30H52N6O2, were analyzed. It was observed that both molecules were stabilized by intramolecular hydrogen bonding. In CDCl3 solution, both molecules mainly enamines were stabilized by an intramolecular hydrogen bond, which was based on 1H, 13C, and 15N NMR measurements. The results show that in both molecules the terminal alkyl grouped arrange in space as centrosymmetric pairs parallel to one another.
