摘要：

In the title molecule, C21H15FN2O2, 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) angstrom] is 83.35 (7)degrees. The pyran ring adopts a slight sofa conformation with the tertiary C(H) atom forming the flap. The methoxy group is slightly twisted from the attached benzene ring of the 4H-benzo[h] chromene moiety [C-O-C-C = -4.3(3)degrees]. In the crystal, molecules are linked by intermolecular N-H center dot center dot center dot N hydrogen bonds into infinite wave-like chains along the b axis. The crystal packing is further stabilized by pi-pi interactions [centroid-centroid distance = 3.7713 (9) angstrom].
