Crystal structure of 3-(2,2-di­bromo­acet­yl)-4-hy­droxy-2H-chromen-2-one

The title compound, C(11)H(6)Br(2)O(4), is a new coumarin derivative obtained from the reaction of 3-acetyl-4-hy­droxy-2H-chromen-2-one with bromine in acetic acid. The hy­droxyl group in involved in an intra­molecular O—H⋯O hydrogen bond. In the crystal, π–π inter­actions between the rings of the b...

description The title compound, C(11)H(6)Br(2)O(4), is a new coumarin derivative obtained from the reaction of 3-acetyl-4-hy­droxy-2H-chromen-2-one with bromine in acetic acid. The hy­droxyl group in involved in an intra­molecular O—H⋯O hydrogen bond. In the crystal, π–π inter­actions between the rings of the bicycle [inter­centroid distances = 3.498 (2) and 3.539 (2) Å] pack mol­ecules into stacks along the b axis, and weak inter­molecular C—H⋯O hydrogen bonds further link these stacks into layers parallel to the ab plane.
