Abstract: The title compound, C12H8F2N2O, crystallizes with two independent molecules in the asymmetric unit. The independent molecules differ slightly in conformation; the dihedral angles between the benzene and pyridine rings are 51.58 (5) and 49.97 (4)°. In the crystal structure, molecules aggregate via N-H...Npyridine interactions as hydrogen-bonded dimers with the structural motif R22(8), and these dimers are linked via C-H...O interactions to form a supramolecular chain.
