Abstract: In the crystal of the title compound, 2C9H8NO+·C4H2Br2O42-·2C4H4Br2O4, the dibromosuccinate dianion and dibromosuccinic acid molecules each lie on an inversion center. They interact via hydrogen bonding. The hydroxyquinolinium cations are hydrogen bonded to both the dibromosuccinate anion and dibromosuccinic acid molecules. The overlapped arrangement and short face-to-face distance of 3.431 (17) Å indicate the existence of - stacking between hydroxyquinolinium rings in the crystal structure.
