1-{(Z)-[3-(1-Hy­droxy­eth­yl)anilino]methyl­idene}naphthalen-2(1H)-one

In the title compound, C(19)H(17)NO(2), the dihedral angle between the benzene ring and the naphthalene ring system is 9.72 (5)°, while the torsion angle of the C—N—C—C bridging group is 179.24 (17)°. The methyl group of the 1-phenyl­ethanol moiety is disordered over two positions with a refined occupancy ratio of 0.775 (5):0.225 (5). The mol­ecular conformation is stabil­ized by an intra­molecular N—H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol­ecules are linked by O—H⋯O hydrogen bonds, forming zigzag chains propagating along the c-axis direction. Neighbouring chains are linked via C—H⋯O inter­actions, forming a two-dimensional slab-like network parallel to the bc plane.
