The title compound, C(12)H(8)F(2)N(2)O, crystallizes with two independent mol-ecules in the asymmetric unit. The independent mol-ecules 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, mol-ecules aggregate via N-H⋯N(pyridine) inter-actions as hydrogen-bonded dimers with the structural motif R(2) (2)(8), and these dimers are linked via C-H⋯O inter-actions to form a supra-molecular chain.
标题化合物C(12)H(8)F(2)N(2)O在不对称单元中结晶出两个独立的分子。这两个独立分子的构象略有不同；苯环和吡啶环之间的二面角分别为51.58 (5)°和49.97 (4)°。在晶体结构中，分子通过N-H⋯N(吡啶)相互作用聚集形成具有R(2) (2)(8)结构基序的氢键二聚体，这些二聚体通过C-H⋯O相互作用连接形成超分子链。
