Crystal structure of (E)-1-{[(3,5-di­methyl­phen­yl)imino]­meth­yl}naphthalen-2-ol

The title compound, C₁₉H₁₇NO, has an E conformation about the N=C bond. The mol­ecule is relatively planar, with the benzene ring and naphthalene ring plane being inclined to one another by 4.28 (10)°. There is an intra­molecular O-HN hydrogen bond generating an S(6) ring motif. In the crystal, mol­ecules are linked via C-HO hydrogen bonds, forming chains propagating along [100]. Within the chains there are - inter­actions involving the benzene ring and the naphthalene ring system of an adjacent mol­ecule [inter-centroid distance = 3.6405 (14) Å].
