In the title compound, C11H6FN3O5, the dihedral angle between the aromatic rings is 72.4 (3)°. The NO2 groups form dihedral angles of 40.8 (2) and 4.8 (2)°, respectively, with the attached pyridine and benzene rings. The crystal structure features - stacking between centrosymmetrically related pairs of pyridine rings [centroid-centroid separation = 3.800 (3) Å].
