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

Abstract

In the title compound, C20H17NO, 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) ？] are observed.
