In the title compound, C27H20F6N2O2, the dihedral angles between the planes of the aromatic rings connected by the ether O atoms are 84.13 (8) and 75.06 (9)°. The crystal structure is stabilized by N-H...O and N-H...F hydrogen bonds. Key indicators: single-crystal X-ray study; T = 173 K; mean σ(C–C) = 0.004 Å; R factor = 0.037; wR factor = 0.088; data-to-parameter ratio = 8.2.
In the title compound, C27H16F6N2O6, the nitro groups are almost coplanar with the aromatic rings to which they are attached [dihedral angles = 3.5 (5) and 6.2 (3)°]. The dihedral angles between adjacent aromatic rings are 78.07 (8) and 71.11 (8)° for nitrophenyl/phenyl and 69.50 (8)° for phenyl/phenyl. An intermolecular C-H...[pi] interaction seems to be effective in the stabilization of the structure. Key indicators: single-crystal X-ray study; T = 173 K; mean σ(C–C) = 0.004 Å; R factor = 0.045; wR factor = 0.092; data-to-parameter ratio = 12.5.
