%X 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  ). Within this system, the 4H-pyran ring adopts a flattened half-chair conformation with the methine C atom lying 0.281 (4)   above the plane of the remaining atoms (r.m.s. deviation = 0.0446  ). The bromobenzene ring is almost perpendicular to the fused-ring system [dihedral angle = 85.34 (13)¡ã]. In the crystal, supramolecular layers parallel to (101) are sustained by amine¨Ccyano N¡ªH...N and amine¨Cmethoxy N¡ªH...O hydrogen bonds. The layers stack with interactions of the type (bromobenzene)C¡ªH...¦Ð(outer-C6 ring of the fused-ring system) connecting them.
