1-[(E)-(2-Phenoxy-Anilino)Methylene]Naphthalen-2(1H)-One

Abstract

The molecule of the title compound, C<inf>23</inf>H<inf>17</inf>NO <inf>2</inf>, a Schiff base derived from 2-hydroxy-1-naphthaldehyde, crystallizes in the keto-amine tautomeric form. The dihedral angle between the aniline and hydroxy-benzene rings is 77.41 (17)°, whereas the planes of the naphthaldehyde and fused aniline benzene rings are nearly coplanar, making a dihedral angle of 8.29 (15)°. Intra-molecular N - H⋯O hydrogen bonding, a characteristic hydrogen bond for Schiff bases, helps to stabilize the molecular structure. Weak intermolecular C - H⋯π interactions are present in the crystal structure. © 2010.
