Crystal structure of 3-bromo­acetyl-6-chloro-2H-1-benzo­pyran-2-one

In the title compound, C11H6BrClO3, the benzo­pyran ring system is essentially planar, with a maximum deviation of 0.036 (2) A for the O atom. The Cl and Br atoms are displaced by −0.0526 (8) and 0.6698 (3) A, respectively, from the mean plane of this ring system. In the crystal, two pairs of weak C—H⋯O hydrogen bonds to the same acceptor O atom link mol­ecules into inversion dimers.
