(E)-4-Methoxy-2-[3-(Trifluoro-methyl)phenyl-imino-methyl]phenol

Abstract

The title compound, C<inf>15</inf>H<inf>12</inf>F<inf>3</inf>NO <inf>2</inf>, adopts the phenol-imine tautomeric form, with the H atom attached to oxygen rather than to nitro-gen. There are two independent mol-ecules aligned nearly parallel in the asymmetric unit with their trifloramethyl groups pointing in opposite directions. The dihedral angles between the aromatic rings are 40.43 (1)° in the first mol-ecule and 36.12 (1)° in the second. Strong intra-molecular O - H⋯N hydrogen bonding generates S(6) ring motifs. Weak inter-molecular C - H⋯O hydrogen bonds link the independent mol-ecules separately into sheets normal to [010]. In addition, C - H⋯π inter-actions are also observed. The F atoms of the trifluoro-methyl groups are disordered over two sets of sites with refined site occupancies of 0.59 (2)/0.41 (2) and 0.62 (3)/0.38 (3), respectively.
