Abstract: The complete molecule of the title compound, C16H14F6N2O2, is generated by crystallographic inversion symmetry, which results in two short intramolecular C-HN hydrogen-bond contacts per molecule. In the crystal, aromatic - stacking [centroid-centroid distance = 3.457 (2) Å] and weak C-H interactions occur. A short HH [2.32 (3) Å] contact is present.
