Low-temperature rerefinement of non­merohedrally twinned tripyridinium bis­[tetra­bromidoferrate(III)] bromide

The asymmetric unit of the title double salt, (C(5)H(6)N)(3)[FeBr(4)](2)Br, consists of three pyridinium cations, two tetra­hedral bromidoferrate(III) anions and a bromide anion. The three cations each form one N—H⋯Br hydrogen bond to the bromide anion. The crystal under investigation was a non-mero...

Sumario:The asymmetric unit of the title double salt, (C(5)H(6)N)(3)[FeBr(4)](2)Br, consists of three pyridinium cations, two tetra­hedral bromidoferrate(III) anions and a bromide anion. The three cations each form one N—H⋯Br hydrogen bond to the bromide anion. The crystal under investigation was a non-merohedral twin, with a portion of 22% for the minor twin component.
