Crystal structure of (E)-1-{[(3,5-di-methyl-phen-yl)imino]-meth-yl}naphthalen-2-ol.

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