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. |
