Abstract
The title compound, C21H15FN2O2, features an approximately planar 1H-benzo[f] chromene fused-ring system (r.m.s. deviation for the 14 non-H atoms = 0.052 angstrom), with the fluorobenzene ring being almost perpendicular to this [dihedral angle = 85.30 (7)degrees]. The furan ring has a flattened half-chair conformation, with the methine C atom deviating by 0.132 (2) angstrom from the plane of the remaining atoms (r.m.s. deviation = 0.0107 angstrom). In the crystal, inversion dimers are formed via pairs of amine-cyano N-H center dot center dot center dot N hydrogen bonds. The dimers are connected into a three-dimensional architecture by C-H center dot center dot center dot N(cyano), C-H center dot center dot center dot pi and pi-pi [intercentroid distance = 3.6671 (10) angstrom] interactions.
