9,9-Dimethyl-12-(4-nitrophenyl)-9,10-dihydro-12H-benzo[a]xanthen-11(8H)-one
In the molecular structure of the title compound, C(25)H(21)NO(4), 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, mol...

| Sumario: | In the molecular structure of the title compound, C(25)H(21)NO(4), 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. |
