In the title compound [also called 5,6-dibromoisoindole-1,3(2H)-dione], C(8)H(3)Br(2)NO(2), there are two planar molecules in the asymmetric unit. They both form inversion dimers, one via N-H...O links and one via short near-linear C-H...O links. The dimers are then linked into chains by further N-H...O hydrogen bonds.
