In the title compound, C10H6F2N4, the Car—N bonds are slightly shortened with respect to a standard aniline C—N bond [1.3580 (16) and 1.3618 (16) versus 1.39 Å], thus indicating some π–π conjgation with the electron-acceptor CN groups. The mol­ecule, except for two C atom of the ethyl­ene bridge, is nearly planar, the largest deviation of the other non-H atoms from the mean plane being 0.309 (2) Å. The N—C—C—N torsion angle involving the ethyl­ene bridge is 50.23 (18)°. In the crystal, mol­ecules are connected by pairs of N—H...N hydrogen bonds into chains along [21-1].
