title: 3,3'-Di-n-propyl-1,1'-[p-phenyl-enebis(methyl-ene)]diimidazolium dibromide.
abstract: The asymmetric unit of the title compound, C(20)H(28)N(4) (2+)·2Br(-), consists of half a 3,3'-di-n-propyl-1,1'-[p-phenyl-enenis(methyl-ene)]diimidazolium cation and a bromide anion. The cation is located on an inversion center and adopts an ⋯AAA⋯ trans conformation. In the crystal, the cation is linked to the anions via weak C-H⋯Br hydrogen bonds.
