| pubmed-article:21583087 | pubmed:abstractText | 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. | lld:pubmed |
