Abstract: In the crystal of the title molecular salt (systematic name: 2-acetylpyridinium 2,5-dibromo-4-hydroxy-3,6-dioxocyclohexa-1,4-dienolate), C₇H₈NO⁺·C₆HBr₂O₄^-, centrosymmetric rings consisting of two cations and two anions are formed, with the components linked by alternating O-HO and N-HO hydrogen bonds. Short OBr contacts [3.243 (2) and 3.359 (2) Å] may help to consolidate the packing.
