(Z)-1-[(3-Cyanophenyl)iminiomethyl]-2-naphtholate

Abstract

The title compound, C18H12N2O, crystallizes in a zwitterionic form. The dihedral angle between the planes of the benzene ring and naphthalene ring system is 13.95 (5)°. An intramolecular N—H...O interaction results in the formation of a planar six-membered ring, which is oriented at dihedral angles of 13.50 (4) and 4.49 (4)° with respect to the benzene ring and naphthalene ring system, respectively. In the crystal structure, intermolecular C—H...O and C—H...N interactions link the molecules into a two-dimensional network. π–π contacts between the naphthalene systems [centroid–centroid distance = 3.974 (1) Å] may further stabilize the structure.
