Secondary interactions in 4-bromo-N,N-dimethylanilinium bromide.
The crystal packing of the title compound, C(8)H(11)BrN(+).Br(-), involves three types of secondary interaction: a classical N-H.Br(-) hydrogen bond, a 'weak' but short C-H.Br(-) interaction (normalized H.Br distance of 2.66 A) and a cation-anion Br.Br contact of 3.6331 (4) A. The hydrogen bonds connect two cations and two anions to form rings of graph set R(4)(2)(14). The Br.Br contacts link these rings to form layers parallel to the bc plane.
