✦ Synopsis

The title compound, C 8 H 12 Br 2 O 4 , has crystallographic inversion symmetry. Molecules adopt a pleated conformation, the OCH 2 -CH 2 CH 2 torsion angles of the butanediol residue being close to 60 and À60 . The molecular packing is stabilized by a network of weak intermolecular hydrogen bonds between the methylene and the carbonyl groups of the bromoacetate units. Each molecule interacts with its four closest neighbours.
