2-Amino-4-(4-bromophenyl)-6-methoxy-4H-benzo[h]chromene-3-carbonitrile

In the title compound, C21H15BrN2O2, the 14 non-H atoms of the 4H-benzo[h] chromene fused-ring system are approximately coplanar (r.m.s. deviation = 0.129 angstrom). Within this system, the 4H-pyran ring adopts a flattened half-chair conformation with the methine C atom lying 0.281 (4) angstrom above the plane of the remaining atoms (r.m.s. deviation = 0.0446 angstrom). The bromobenzene ring is almost perpendicular to the fused-ring system [dihedral angle = 85.34 (13)degrees]. In the crystal, supramolecular layers parallel to (101) are sustained by amine-cyano N-H center dot center dot center dot N and amine-methoxy N-H center dot center dot center dot O hydrogen bonds. The layers stack with interactions of the type (bromobenzene) C-H center dot center dot center dot pi (outer-C-6 ring of the fused-ring system) connecting them.
