2-[(E)-2-Hy-droxy-5-(trifluoro-meth-oxy)benzyl-idene-amino]-4-methyl-phenol

Abstract

The title compound, C15H12F3NO3, is a Schiff base which adopts the cis-quinoid form in the solid state. The dihedral angle between the least-squares planes of the benzene rings being 3.6 (1)degrees. The F atoms of the -CF3 group are disordered over two sets of sites with refined occupancies of 0.61 (5) and 0.39 (5). An intramolecular N-H center dot center dot center dot O hydrogen bond occurs. The crystal structure is stabilized by intermolecular O-H center dot center dot center dot O hydrogen bonds.
