A second polymorph of 3,5-dibromopyridinium bromide

P. G. Jones and V. Lozano

Abstract: All atoms of the title compound, C₅H₄Br₂N⁺·Br^-, lie in a crystallographic mirror plane. The packing within the plane is determined by hydrogen bonds N⁺-HBr^- and C-HBr^-, and by BrBr contacts, but differs from that of the previous polymorph [Freytag & Jones (2001). Z. Naturforsch. Teil B, 56, 889-869], which also lay completely in mirror planes.
