Crystal structure of N-[(2-hydroxynaphthalen-1-yl)(4-methylphenyl)methyl]acetamide

Abstract

In the title molecule, C20H19NO2, the naphthalene ring system subtends a dihedral angle of 82.50 (7)° with the benzene ring and an intramolecular N—H...O hydrogen bond closes an S(6) ring. In the crystal, molecules are linked by O—H...O hydrogen bonds, which generate C(8) chains propagating in the [010] direction. The crystal structure also features weak π–π interactions [centroid–centroid separation = 3.7246 (10) Å].
