چکیده
In the title mol-ecule, C(21)H(15)FN(2)O(2), the dihedral angle between the fluoro-substituted benzene ring and the mean plane of the 4H-benzo[h]chromene ring system [maximum deviation = 0.109 (2) Å] is 83.35 (7)°. The pyran ring adopts a slight sofa conformation with the tertiary C(H) atom forming the flap. The meth-oxy group is slightly twisted from the attached benzene ring of the 4H-benzo[h]chromene moiety [C-O-C-C = -4.3 (3)°]. In the crystal, mol-ecules are linked by inter-molecular N-H⋯N hydrogen bonds into infinite wave-like chains along the b axis. The crystal packing is further stabilized by π-π inter-actions [centroid-centroid distance = 3.7713 (9) Å].
