The title Schiff base compound, C15H15NO2, crystallized as the iminium–phenolate zwitterion. The H atom is localized on the imine N atom, forming a strong intramolecular hydrogen bond with the phenolate O atom, and giving rise to an S(6) ring motif

The effect of the nitrogen nonbonding electron pair on the 1JC,H values of 1,3-diazaheterocycles was analyzed and compared to 1,5-diazabiciclo[3.2.1]octanes, which have a restricted conformation. The 1JC,H values were measured by observing the 13C sa
