The title compound, C8H14Br2N2O2, lies about an inversion centre and adopts a pleated conformation, with the C(O)Ð NHÐCH2ÐCH2 and NHÐCH2ÐCH2ÐCH2 torsion angles of the butanediamine residue being ÿ89.5 (6) and ÿ62.1 (7) , respectively. These data are useful in discerning the structure of polymers containing such a unit. A skew conformation is found for the BrÐCH2ÐC(O)ÐNH torsion angle [ÿ124.2 (4) ]. The molecular packing is stabilized by strong hydrogen bonds between amide groups and also by weak CH2 OC interactions. In this way, each molecule interacts with its six closest neighbours through eight hydrogen bonds.
