(E)-4-Methoxy-2-[3-(trifluoromethyl)phenyliminomethyl]phenol
Özet
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 nitrogen. There are two independent molecules 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)degrees in the first molecule and 36.12 (1)degrees in the second. Strong intramolecular O-H center dot center dot center dot N hydrogen bonding generates S(6) ring motifs. Weak intermolecular C-H center dot center dot center dot O hydrogen bonds link the independent molecules separately into sheets normal to [010]. In addition, C-H center dot center dot center dot pi interactions are also observed. The F atoms of the trifluoromethyl 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.
