6-Chloro-3-(2,2-dibromoacetyl)-2H-chromen-2-one

6-Chloro-3-(2,2-dibromoacetyl)-2H-chromen-2-one

In the title compound, C11H5Br2ClO3, the benzopyran ring system is essentially planar (r.m.s. deviation = 0.023 Å) and one of the bromine atoms is almost coplanar with it [deviation = 0.091 (1) Å]. In the crystal, inversion dimers linked by pairs of double-acceptor (C—H)2...O hydrogen bonds are seen...
