In the title compound, C11H8O3, the fused-ring system is almost planar (r.m.s. deviation = 0.020 Å), with the largest deviation from the least-squares plane [0.0462 (17) Å] being for a pyran C atom. The dihedral angle between the plane of the fused-ring system and acetyl plane is 5.149 (16)°. In the crystal, the fused rings are linked by aromatic π–π stacking interactions [centroid–centroid distance between the benzene and pyran rings = 3.643 (6) Å] and C—H⋯O hydrogen bonds, generating a three-dimensional network.
Keywords: crystal structure; chromone; hydrogen bond; π–π stacking.

The title compound was synthesized from 3-(dimethylamino)-1-(2-hydroxyphenyl)prop-2-enone (Li et al. 2012) according to the literature method (Yokoe et al. 1994). Single crystals suitable for X-ray diffraction were obtained by slow evaporation of an ethyl acetate solution of the title compound at room temperature.
All hydrogen atoms were placed in geometrical positions [C–H 0.95 and 0.98 Å], and refined using a riding model with Uiso(H) = 1.2Ueq of the parent atoms. The s.u.s for the cell parameters are rather large, possibly due to frost damage to the crystal.

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 σ(F2) is used only for calculating R-factor (gt). |

Many derivatives of the title compound are reported because of their chemical, biological and medicinal significance (Yokoe et al. 1994, Chanda et al. 2014).
The mean deviation of the least-square plane for the non-hydrogen atoms of the fused-ring is 0.0201 Å, and the largest deviation from the plane is 0.0462 (17) Å for C2. These mean that these atoms are essentially coplanar (Fig.1). The dihedral angle between the fused-ring and acetyl plane is 5.149 (16) Å.
In the crystal, the molecules are linked by π–π stacking [centroid–centroid distance between the benzene and pyran rings = 3.643 (6) Å], and C–H···O hydrogen bonds form sheets along [0 4 1] and [0 4 1], as shown in Fig.2 and Fig.3.
The crystal structure of a 2,5,6,7-substituted 3-acetylchromone derivative is reported (Chanda et al. 2014).
