Abstract

In the crystal structure of the title compound, C20H38N22+·2Br−, the centroid of the aromatic ring is located on an inversion center, so that the asymmetric unit consists of one-half mol­ecule of the dication and one bromide anion. C—H⋯Br inter­actions connect the two components into a three-dimensional network. An intra­molecular C—H⋯π inter­action is also observed.
