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

The title compound, C(19)H(17)NO, 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—H⋯N hydrogen bond generating an S(6) ring motif. In the crystal, mol­ecules are linked via C—H⋯O hydrogen bonds, forming chains propagating along [100]. Within the chains there are π–π inter­actions involving the benzene ring and the naphthalene ring system of an adjacent mol­ecule [inter-centroid distance = 3.6405 (14) Å].
