In the crystal of the title mol-ecular salt (systematic name: 2-acetyl-pyridinium 2,5-dibromo-4-hydr-oxy-3,6-dioxocyclo-hexa-1,4-dienolate), C(7)H(8)NO(+)·C(6)HBr(2)O(4) (-), centrosymmetric rings consisting of two cations and two anions are formed, with the components linked by alternating O-H⋯O and N-H⋯O hydrogen bonds. Short O⋯Br contacts [3.243 (2) and 3.359 (2) Å] may help to consolidate the packing.
在标题分子盐（系统名称：2-乙酰基吡啶鎓 2,5-二溴-4-羟基-3,6-二氧代环己-1,4-二烯醇盐）C₇H₈NO⁺·C₆HBr₂O₄⁻的晶体中，形成了由两个阳离子和两个阴离子组成的中心对称环，各组分通过交替的O—H⋯O和N—H⋯O氢键相连。短的O⋯Br接触 [3.243 (2) 和 3.359 (2) Å] 可能有助于巩固堆积。
