摘要：

In the title compound, C19H14FN3O 3, the central pyran ring adopts a boat conformation with the O atom and the quaternary C atom diagonally opposite displaced by 0.068 (1) and 0.075 (1) Å, respectively, above the mean plane defined by the other four ring atoms. The co-planar atoms of the pyran ring and the fluorophenyl ring are nearly perpendicular, as evidenced by the dihedral angle of 87.11 (1)°. The amine group forms an intramolecular N - H⋯O(nitro) hydrogen bond. In the crystal, molecules are linked into parallel chains along [100] by weak N - H⋯N and C - H⋯N(nitro) hydrogen bonds, generating C(8) and C(9) graph-set motifs, respectively.
