2-Amino-4-(4-bromophenyl)-6-methoxy-4H-benzo[h]chromene-3-carbonitrile
In the title compound, C(21)H(15)BrN(2)O(2), 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 p...

Sumario: | In the title compound, C(21)H(15)BrN(2)O(2), 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 bromobenzene ring is almost perpendicular to the fused-ring system [dihedral angle = 85.34 (13)°]. In the crystal, supramolecular layers parallel to (101) are sustained by amine–cyano N—H⋯N and amine–methoxy N—H⋯O hydrogen bonds. The layers stack with interactions of the type (bromobenzene)C—H⋯π(outer-C(6) ring of the fused-ring system) connecting them. |
