2-[(E)-(Naphthalen-2-yl-imino)-meth-yl]-4-(trifluoro-meth-oxy)phenol.

In the title compound, C18H12F3NO2, the planes of the benzene ring and the naphthalene system form a dihedral angle of 47.21 (3)°. The hy­droxy group is involved in an intra­molecular O—H⋯N hydrogen bond. In the crystal, weak C—H⋯O and C—H⋯F inter­actions link the mol­ecules related by translations along the c and a axes, respectively, into sheets.
