چکیده
In the title compound, C11H6BrClO3, the benzo-pyran ring system is essentially planar, with a maximum deviation of 0.036 (2) Å for the O atom. The Cl and Br atoms are displaced by -0.0526 (8) and 0.6698 (3) Å, 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 mol-ecules into inversion dimers.
