3-(Ammoniomethyl)pyridinium dibromide [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 In the title salt, C(6)H(10)N(2) (2+)·2Br(-), the non-H atoms of the 3-methyl-pyridinium unit of the cation are almost coplanar (r.m.s. deviation = 0.0052 Å). In the crystal, the dications and Br anions are linked by a combination of six hydrogen bonds, viz.
