Abstract
In the title compound, C15H15NO, the configuration of the C=N bond of the Schiff base is E, and an intramolecular O—H⋯N hydrogen bond is observed, forming an intramolecular S(6) ring motif. The phenol ring is inclined by 45.73 (2)° from the plane of the aniline ring. In the crystal, molecules are linked along the b axis by O—H⋯N and C—H⋯O hydrogen bonds, forming polymeric chains. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the packing arrangement are from H⋯H (56.9%) and H⋯C/C⋯H (31.2%) interactions. The density functional theory (DFT) optimized structure at the B3LYP/ 6–311 G(d,p) level is compared with the experimentally determined molecular structure, and the HOMO–LUMO energy gap is provided. The crystal studied was refined as an inversion twin.
