Crystal structure of (E)-N-[(E)-3-(4-meth­oxy­phen­yl)allyl­idene]naphthalen-1-amine

In the title compound, C(20)H(17)NO, the dihedral angle between the mean planes of the 4-meth­oxy­phenyl ring and the naphthalene ring is 69.50 (7)°. The meth­oxy group is almost coplanar with the benzene ring to which it is connected [Cb—Cb—Om—Cm torsion angle of −7.9 (2)°; b = benzene and m = meth­oxy] and the imine group displays a C—C—N=C torsion angle is −57.2 (2)°. The imine (C=N) group has an E conformation. In the crystal, weak π–π inter­actions between the benzene rings [centroid–centroid distance = 3.7781 (10) Å] are observed.
