1,1′,2,2′,3,3′,4,4′-Octamethylferrocenium 2,5-dibromo-4-hydroxy-3,6-dioxocyclohexa-1,4-dien-1-olate

Abstract

In the title salt, octamethylferrocenium bromanilate, [Fe(C9H13)2](C6HBr2O4), the Fe atom and the bromanilate anion lie on a mirror plane. The octamethylferrocenium cation adopts an eclipsed conformation. An intramolecular 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].
