Despite the oxyimino chain being unconjugated [N-O 1.434 (2) and C-N 1.278 (2) angstrom] in the title compound, C13H8F4N2O, the planar alpha-phenylethylimino and tetrafluoro-2-oxopyridine moieties are only slightly twisted relative to each other [C-O-N-C 167.6 (2)-degrees]. This facilitates stacking along the ac diagonal so that fluorinated pyridine substituents alternate with non-fluorinated phenyl rings.
