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...

description 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.
