چکیده
The title compound, C(15)H(12)F(3)NO(2), 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.
