| Summary: | 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) Å] is 83.35 (7)°. 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)°]. In the crystal, molecules are linked by intermolecular N—H...N hydrogen bonds into infinite wave-like chains along the b axis. The crystal packing is further stabilized by π–π interactions [centroid–centroid distance = 3.7713 (9) Å]. |
