Abstract
In the molecular structure of the title compound, C25H21NO4, the pyran ring adopts a flattened boat conformation, while the cyclohexenone ring is in an envelope conformation. The 4-nitrophenyl ring is almost perpendicular to the pyran ring [dihedral angle = 89.39 (1)°]. In the crystal, molecules are connected by intermolecular C—H⋯O hydrogen bonds.
