3,4-Dihydro-1H-benzo[c]chromene-1,6(2H)-dione
In the title compound, C(13)H(10)O(3), the pyranone and benzene rings are almost coplanar, making a dihedral angle of 1.9 (1)°. The cyclohexenone ring adopts an envelope conformation, with a methylene C atom located at the flap and displaced by 0.639 (3) Å from the mean plane of the other five at...

| Sumario: | In the title compound, C(13)H(10)O(3), the pyranone and benzene rings are almost coplanar, making a dihedral angle of 1.9 (1)°. The cyclohexenone ring adopts an envelope conformation, with a methylene C atom located at the flap and displaced by 0.639 (3) Å from the mean plane of the other five atoms. In the crystal, pairs of weak C—H⋯π interactions occur between inversion-related molecules. |
