چکیده

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 Å). Within this system, the 4H-pyran ring adopts a flattened half-chair conformation with the methine C atom lying 0.281 (4) Å above the plane of the remaining atoms (r.m.s. deviation = 0.0446 Å). The bromo-benzene ring is almost perpendicular to the fused-ring system [dihedral angle = 85.34 (13)°]. In the crystal, supra-molecular layers parallel to (101) are sustained by amine-cyano N-H⋯N and amine-meth-oxy N-H⋯O hydrogen bonds. The layers stack with inter-actions of the type (bromo-benzene)C-H⋯π(outer-C6 ring of the fused-ring system) connecting them.
