Abstract: The molecule of the title compound, C₁₉H₂₀F₃N₃O₅, at 150 K, is nearly planar and exists in the keto-amine (N-HO) tautomeric form, with a strong intramolecular hydrogen bond of 2.585 (2) Å between the O and N atoms. The configuration around the azo -N=N- double bond is trans, as found for other diazene derivatives, and the dihedral angle between the planes of the two aromatic rings is 7.81 (4)°.
