Hydrogen bonding in (2-bromobenzyl)dimethylammonium bromide

R. A. Varga and C. Silvestru

Abstract: Ions of the title compound, C₉H₁₃BrN⁺·Br^-, are linked by a strong N-HBr^- hydrogen bond, and this unit is further linked to another three anion-cation units by weak C-HBr^- contacts (HBr range 2.95-3.09 Å), generating a two-dimensional layer parallel to the bc plane. The layers are stacked along the a axis without any interactions in the third dimension. The Br atom of the cation forms only an intramolecular hydrogen bond (HBr = 2.76 Å) with one of the methylene H atoms.
