3-Acetyl-4-hy­droxy-6,7-dimethyl-2H-chromen-2-one

In the title coumarin derivative, C(13)H(12)O(4), the 2H-chromene ring system is essentially planar [maximum deviation = 0.047 (1) Å]. An intra­molecular hydrogen bond is observed between the hy­droxy and the ketonic O atoms. In the crystal, pairs of inter­molecular C—H⋯O hydrogen bonds link inversi...

description In the title coumarin derivative, C(13)H(12)O(4), the 2H-chromene ring system is essentially planar [maximum deviation = 0.047 (1) Å]. An intra­molecular hydrogen bond is observed between the hy­droxy and the ketonic O atoms. In the crystal, pairs of inter­molecular C—H⋯O hydrogen bonds link inversion-related mol­ecules into dimers. Additional inter­molecular C—H⋯O hydrogen bonds further inter­connect these dimers into two-dimensional arrays incorporating R (2) (2)(9) ring motifs.
