Crystal structure of 1-{(E)-[(3,4-dichlorophenyl)imino]methyl}naphthalen-2-ol

In the title compound, C17H11Cl2NO, the dihedral angle between the planes of the naphthalene ring system and the benzene ring is 28.88 (11)°. The main twist in the molecule occurs about the N—Cb (b = benzene ring) bond, as indicated by the C=N—Cb—Cb torsion angle of 31.0 (4)°. An intramolecular O—H...N hydrogen bond closes an S(6) ring. In the crystal, inversion dimers linked by pairs of very weak C—H...O interactions generate R22(16) loops.
