Abstract: The crystal structure of the title compound, C₂₀H₁₅FN₂O₂, contains two crystallographically independent molecules, which are related by a pseudo-inversion center and linked into dimers via intermolecular N-HN hydrogen bonds. The 4-fluorophenyl ring of molecule A makes dihedral angles of 17.17 (16) and 62.25 (15)°, respectively, with the phenyl and pyridine rings. The 4-fluorophenyl ring of molecule B makes dihedral angles of 8.50 (16) and 64.59 (15)°, respectively, with the phenyl and pyridine rings. The dihedral angle between the pyridine ring and the phenyl ring of molecule A [60.97 (15)°] is bigger than in molecule B [59.49 (15)°]. The dihedral angle between the two pyridine rings is 1.37 (14)° and between the two phenyl rings is 3.64 (16)°.
