title: Bis(2-chloro-benz-yl)dimethyl-ammonium bromide.
abstract: In the title compound, C(16)H(18)Cl(2)N(+)·Br(-), the dihedral angle between the aromatic ring planes is 57.73 (5)°. In the absence of any strong hydrogen bonds, the structure results from a large number of competing weaker inter-actions including Cl⋯Cl [3.4610 (5) Å] and C-H⋯Cl contacts and both (aryl) C-H⋯Br and N(+)-Csp(3)-H⋯Br(-) cation-anion inter-actions.
