title: 1,1',2,2',3,3',4,4'-Octa-methyl-ferro-cenium 2,5-dibromo-4-hy-droxy-3,6-dioxocyclo-hexa-1,4-dien-1-olate.
abstract: In the title salt, octa-methyl-ferrocenium bromanilate, [Fe(C(9)H(13))(2)](C(6)HBr(2)O(4)), the Fe atom and the bromanilate anion lie on a mirror plane. The octa-methyl-ferrocenium cation adopts an eclipsed conformation. An intra-molecular O-H⋯O hydrogen bond is present in the bromanilate anion. In the crystal, the cations and anions are stacked alternately, forming a one-dimensional columnar structure along [010].
