Crystal structure of 3-bromo-acetyl-6-chloro-2H-1-benzo-pyran-2-one.

ABSTRACT: 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.

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. ...[more]
