8-Acetyl-4-methyl-2-oxo-2H-chromen-7-yl acetate

In the title compound, C(14)H(12)O(5), the benzopyran-2-one ring system is approximately planar [maximum deviation = 0.018 (1) Å]; the mean plane is oriented at dihedral angles of 52.26 (11) and 72.92 (7)°, respectively, to the acetyl and acet­oxy groups. In the crystal, π–π stacking is observed bet...

description In the title compound, C(14)H(12)O(5), the benzopyran-2-one ring system is approximately planar [maximum deviation = 0.018 (1) Å]; the mean plane is oriented at dihedral angles of 52.26 (11) and 72.92 (7)°, respectively, to the acetyl and acet­oxy groups. In the crystal, π–π stacking is observed between parallel benzene rings of adjacent mol­ecules, the centroid–centroid distance being 3.6774 (17) Å. Inter­molecular weak C—H⋯O hydrogen bonding, and C=O⋯C=O [O⋯C = 3.058 (3) Å] and C=O⋯π [O⋯centroid = 3.328 (2) Å] inter­actions occur in the crystal structure.
