The asymmetric unit of the title compound, C18H10F4N2O, is composed of two identical molecules having different configurations. Although both molecules adopt a trans configuration about the N-O bond [C-N-O-C 164.2 (3) and -162.0 (2)-degrees], substantial twists of all the aromatic rings relative to the C=N-O plane show no correlation between the conformers. Despite the apparently random molecular configurations, the packing arrangement involves several pi interactions between adjacent molecules.
