Abstract

In the title mol-ecule, C(11)H(6)F(2)N(2)O(2), the benzene and pyridine rings form a dihedral angle of 32.57 (6)°. The nitro group is tilted with respect to the pyridine ring by 12.26 (9)°. An intra-molecular C-H⋯F hydrogen bond is present. In the crystal, mol-ecules inter-act through π-π stacking inter-actions [centroid-centroid distances = 3.7457 (14) Å], forming columnar arrangements along the b axis. The crystal packing is further enforced by inter-molecular C-H⋯O and C-H⋯N hydrogen bonds.
